Hello all....

 

I bought a 2007 Silverado LTZ crew cab a few months back. I have a couple problems with it.

 

 

PROBLEM #1:

It seems that the in dash CD Changer does not work. I don't know if there is a CD stuck in it or what. I cannot load any CDs into it and when I try the eject button it makes some moving noises and give me a "Check CD" error. By the looks of things the display tells me there is a CD in # 1 slot. Can anyone tell me how to check to see if there is an actual CD stuck in it. How do I get into to the changer? or if you have any other ideas please let me know.

 

 

PROBLEM # 2:

My truck has an RSA (rear seat audio) unit in it. I cannot get this to work at all. It is like there is no power to it. No display and nothing happens when I hit the power button.

 

 

PROBLEM #3:

Sometimes when I jump in my truck and start it up the radio is not on (even though I left it on), also until I turn the radio power on my signal lights make no sound in the cab and my back up sensors are turned off. Once I hit the radio power button it all goes back to normal.

 

I do not know if the problems are related to one another or not. If anyone has any ideas let me know. Thanks.

 

Oh I have checked the applicable fuses and I believe they are all fine.

You do not say but it sounds like you have an aftermarket radio/HU.

1) Not sure about the the CD error issue but it sounds like something is in there. You will probably need to take the HU out and at least take the cover off to see if anything is in there.

2) If it is an aftermarket HU, it will not have the right interface for the GMLAN, unless it is a Rosen, and even if it is a Rosen you will not be able to use the RSE. You will need something like a PAC Audio OS-4 with GMRVD cable to breakout the RSE to interface with the HU properly.

3) All of the chimes and tones are made by the HU on your model year. Not sure though why they are not making a sound when the HU is "off". If it is a aftermarket that may be the answer.

 

I am willing to bet your steering wheel controls do not work also.

 

So the big question is- what kind of HU do you have?

Thanks for helping. I do have the factory radio / Cd Changer, no aftermarket at all.

 

My steering wheel controls do work just fine.

 

I have thought about trying to get into the changer but I do not know how to get to it. I think the plastic wood grain looking trim around the radio comes off but I did not want to break it.

 

I have check the fuses, and tried the old disconnect the battery for an hour trick, but nothing seems to work for any of my problems. I was able to pull the RSA out and disconnect and reconnect it but no luck either.... I really don't know where to go from here.....

 

Anyway, now that you know it is the factory radio what do you think??????

My second guess is that whoever had the truck before had a problem (or not) with that HU and put in an aftermarket. When he sold the truck he put the OEM back in and maybe did not reconnect everything. Just a guess though.

 

You can pull the woodgrain trim off by getting a small screw driver and prying it out from the side. I will seem like it is going to break but if you get close to the clips it should not. You can also get some plastic pry tools from Harbor Freight if you have one near. There are some youtube videos you can search for to remove it. I have a picture of mine removed in this thread

http://www.tahoeyukonforum.com/forum/showt...8910&page=4 if you want to go there and look at it already out and see where the clips are.

Ok so I took a look at your pic tonight. I took the trim off the dash and removed the radio. I plugged it back in just in case it was something stupid, but no luck, same thing. I then removed the radio took it in the house and opened it up. I found a dollar coin in it (loonie)! Can you believe that. It was jamming the changer up. I removed it and away it went, just like.

 

Now If I could get this back seat radio issue solved I would be set. Still no power to the unit? I have no idea why..... I would guess it uses the same fuse as the radio.... I might have to take it to the dealer for this one......

 

Anyway I just wanted to thank you for your help......

 

If you should have any ideas on the rsa let me know. Thanks again!

Funny about the dollar :chevy:, I bet the other owner had small kids. So far I have been batting 0 for 2 on this one so not so sure you should listen, but you might try calling or going by the dealer and asking them what they think the problem may be. Sometimes they will give you something to go on and sometimes not.

Do you have the Nav unit with four connectors on the back plus the two antenna connections?

No NAV unit, just a plain and simple radio interface that allows the back seat passengers to listen to the radio and or the cd with ear phones. I pulled it off the center console the other day. It has two plugs in the back. I unplugged them and then plugged them back in. No luck. Do you think it my be on a different fuse then the radio? That is all I can think of. I'll attach a pic of the RSA.....

you have pressed the power button on it right?

 

could be a burned out unit, I saw some on ebay for like $30

 

 

as far as the fuse, check the owners manual.. if you don't have it go to Chevy.com and click the FOR OWNERS link, you can download the manuals in PDF.

Did you check to see if that power port below the unit has power? I bet they share a power source. You could also take the RSE out and see if it has power to it. Switched power is usually solid red wire.

 

Good find old-chevy-dude, I did not know those manuals were there. If only they would put the maintenance manuals too!

Hey first thanks again for you help guys....

 

I have check the power port and it does have power.

 

Nothing in the manual refers to the RSA and its fuse just the radio.

 

I will look more closely into the fuse thing tomorrow.

 

 

ptwat - How do I go about finding out if its has power????? Do you have to put a meter on it or something like that?

You would need to get a cheap voltmeter (Radio Shack, Fry's or others). Or you could even use a 12 volt tail lamp with wires soldered to it or use a replacement socket and lamp from pep boys or other parts store.

Once you have the RSE/RSA out look for the metal part of the wire on the back of the connector to it and put the red voltmeter on it and the black lead of the voltmeter on a ground (a screw head into the chassis like at the bottom of the seat). The voltmeter should read around 12V to 14V if it is powered. Try it with the truck in ACC position. You can check all of the wires but power is probably solid red. If you have power and there is still no display (and you have tried all the knobs and buttons on the RSE) you probably have a dud.

Still have not tested the power...... but,

 

I can't seem to find any of the RSA's on ebay or anywhere. Can anyone point me in the right direction??????

Well finally borrowed a multimeter and tested the power to the RSA. Lot's of power there. I took the RSA apart and did not find any burn marks on the circuit boards. No luck getting it working looks like I am in the market for a new RSA unit.......

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
