Is there somewhere anyone knows in the greater Houston area that I can get an illumination problem fixed on my 01 Tahoe? Some buttons on my factory radio won't illuminate at night.

Gentlemen,

 

I just replaced all bulbs in my delco radio with Radio shack bulbs..Excellent results but buy some solder wick and you better know how to solder.

Just some buttons? If so its an out bulb if you can solders you can do it yourself. I've done mine plenty of times along with others on here. If you don't want to do that look on eBay for a replacement, it might be cheaper and easier than getting yours fixed.

Gentlemen,

 

It really was easy, much easier than I thought, but you do need to know how to solder.

 

you need a small soldering iron 50 watts or so and some desoldering wick. Radio shack has the bulbs for 1.50 each, you need ten. Replace the bulbs in the a/c control head too, they are even easier.

 

When you are done, you can read by the radio lights. Cool. If you can solder or are trainable, super easy. Entire replacement radio may also have used up bulbs.

Those look prety cool..............where did you get the bulbs?.........I have a few out and if im going to replace them I would rather go with LED's....... :banghead:

I just went down to the local electronics store and picked up some LEDs....

 

Here is a parts list

 

Radio

10 LEDs

3-5mm 4-7000 MCD with a forward voltage of 3.5v

10 Resistors

230-1000 OHm Depending on how bright or dim you want it.

I find 270 to be just fine.

 

 

HVAC

It's been awhile but I believe 7 LEDs

With the same specs as the Radio.

3-5mm 4-7000 MCD with a forward voltage of 3.5v

Resistors

230-1000 OHm Depending on how bright or dim you want it.

I find 270 to be just fine.

 

Cheers

Looks good, what gallery are the pics in? I found it a little tight in there, where did you make room for the resistor? Could you give some more details on this?

The only way I could get the resistors to fit was to put one side of the resistor down into the socket then 90 it so the resistor was parallel to the board and then 180 the other side of the resistor and run it up to the LED.

Make sense?

See here how I have Red Electrical tape on the resistor that's so it doesn't short out. If I was really good I would have used heatshrink...

 

Let me know if you have more questions..

That helps a lot, in the one pic it looked a little dim to my taste, would I need a higher number resistor or lower (270 vs. ? for brighter)? I can solder but never any resistors or LED's It looks like Polarity matters +/- how well are LED's and resistors marked for this? On the bulbs I just put them ever which way...

 

P.S. I will probably do red if anything, not tht it matters. I'm glad to see those pics, I've been debating with myself about doing this.

It's actually just the picture it's really easy to see at night but, if you want it a tad brighter go with a smaller resistor. Polarity does matter I hope that my little diagram with polarity helps.

 

Resistors don't matter when it comes to polarity but, with LEDs it does. The way I figured out which side of the LED was + and which was - was just to try it. Just take one LED and a resistor and try it on the battery. Once you got that figured out it's really easy. Just make sure you use a resistor every time as it's easy to smoke an LED without a resistor.

 

Hope to see some pics after you do it.

I posted the directions and the contact info in the tech section. If you use the Radio Shack lights, they do not last and are not the same brightness. Just My opnion.

Forgive my ignorance, but where is the tech section, how do I get to it?

 

Thanks.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
