I just got a 02 3500 crew cab and it doesn't have the towing mirrors option like I see on some of them. I would lke to convert over to the better mirrors but I'm not sure of all the details. It would be nice to have a plug and play situation but I know better. I'm sure that there should be more switches to run the mirrors to extended phase, but not sure how it all all works. Thanks for the help. Scott

I'm not sure myself. We don't do swaps like this so I have no experience with it. And, I think I've only seen one truck with these mirrors.

Actually it doesn't take any more switches. You simply put the selector for which mirror you want to control in the center "neither" position . . . pressing the outboard side of the mirror adjuster switch (as if to adjust the mirror to the left) will make the mirrors extend and pressing the inboard side will make them retract. That's how it works on my father-in-laws 2003 2500HD. I have heard that you simply plug the mirrors in and bolt them on, and then have the BCM reflashed to enable the mirrors if they happen not to work after plugging them in. :devil:

That is true if the truck already has the power fold mirrors, but if it doesn't then you have to replace the DDM (drivers door module) and program the BCM for it.

I have changed them on my 04 2500hd, it came only with power heated mirrors..

I wanted the blinker heated power extending.. I got them and they plugged right in to the Door Modules... No Need to replace them on 2003-2005 years anyway, Not sure of them earlier years.

I then went to the dealer and 10 minutes later they was running!! I have since removed them from the 04 and put them on my 05 with the same results.. Plug in Program and All is good..

 

I thought the switch may need replaced but on both mine the mirror selector switch had 3 positions, Left-Center-Right. anyway it works..

 

now I do not know about other years.. My mirrors was off a 03, and was on my 04 and now on my 05.. so these 3 years are plug program and play...

 

>>>One other thing would be your truck would need to have power mirrors already? both mine had just the basic power heated on them. if you have No Power mirrors on your truck then it may be a job..

However there are aftermarket extending mirrors that should be easy to install..

Powervison, or they have some manual extending mirrors<<<

 

Good Luck

Well I finally found one of the mirrors I need. Now for some new questions. I do not have power folding mirrors so it sounds like I need to replace the drivers door module and get the BCM flashed. The first question is could te DDM go by a different name, I have been doing a search to find out a part number and price but have had no luck yet. The second is when I get the second mirror and install it, will I have to go through another reflash? Thanks Scott

Not sure of any other name for the DDM, but yes when you get a second you will need to do the flash again..

This last time my dealer done mine he done just the drivers side and the other side did not work right.. caught it when I got home.

anyway its in the door modules that they program, Also Mine did not have the folding mirrors either and I did Not have to replace the module or switches... this was in my 04 and in my current 05... they did have power heated but that was it.

Maybe I can get lucky and not have to get the door module. I hope that the 02 is the same as the 04 when it comes to this item. I also have the power heated mirrors and not the folding version. I'll let you know when the mirror gets here and I get it bolted up.

Here's a new dilema. The new towing mirror came in and everything looked fine. when I went to pull off the old mirror I noticed it has one black connector to unplug but the towing mirror has two different plugs. The first one is a black connector but not the same exact end to match up and the second is a blue connector that I don't have any clue to what it connects to. Any ideas would be appreciated. I really do want to use these bad boys. Thanks Scott

on my door module there is 2 sockets for the 2 plugs.. My original mirrors just had the one plug as well, and the new mirrors 2 plugs. if you look or feel you will find the other slot to plug into.

I hope you can use them without problem.. like I say before mine was on a 04 and 05.. in which I had no trouble with either.

 

Keep Us posted.. sorry it took awhile getting back to you..

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      By glenn27 · Posted

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.
