First post so be kind if I leave information out

I have 08 Sierra SLE. I was wondering if I could get power heated mirrors added to my truck

I do have power mirrors but heated would be very nice. Is there wires in my truck to add the option kind of like adding the DIC or is it a major issue?

 

Thanks

Welcome!

 

Can't you your answer from any experience, but I would think that it's highly possible that the wires would be there. Remove the inside cover on the door where the mirror is connected and see if there is a wire that is not connected to anything.

Do you have a rear-window defrost now ? That definitely would be required.

Ted,I think you already have heated mirrors and not even know it...Look inside your glovebox and see if you have RPO code "DL8",If you do then they are heated,You use the rear defogger switch to turn them on.

Yeah,All GMT900 power mirrors are heated,Thats why I wanted you to check your RPO codes first.

Rich, my '09 has the PDD Exterior Plus Package, which gives me the upgraded mirrors. But, I don't have the lines in the back window for the rear defogger. Do my heated mirrors turn on automatically?

Mine doesnt have the rear defog lines on the back window either. Right under the display for the climate control, there's a small button (beside the A/C snowflake button) with a picture of a mirror and wavy lines. :confused:

Bingo,Thats it...You'll have a mirror symbol (in place of the rear defogger symbol) but there is a switch for them,and you must turn them on manually.

Just question that is somewhat connected to the others are the mirrors already wired for the ones with the turn signals in them. If so can you just purchase them and connect and thats that? Thanks

What about on the GMT800 trucks? I'm not sure if mine are heated too or not? I do have the defroster button for the rear window, but am not sure if they had the mirrors heated in this model truck.

 

Thanks!

No,The GMT800's had both power mirrors with heat,and just power mirrors with no heat (although most '03-up had heat)

Look for one of two RPO codes..... D48 - power w/o heat or DL8 - power w/heat.

Also don't forget about RPO DL3 which is power w/heat and also features turn-signal w/power-fold.

Some are and some aren't,It depends on trim level and options on the truck,In most cases the DL3 mirrors will plug in and the turn-signal feature will work with no issues,but the power-fold feature will not.

My 2010 Sierra SLE had the DL8 mirrors, power and heated but no signals. I bought the Kool Vue towing mirrors with signals and with only plugging them in, the signals now work also.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
