Power Heated Mirrors

[master4.8]

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.

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.

Found it! Guess I never really looked very hard, because I haven't needed to use them yet. Thanks guys!

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.

Thank you MS3Dale, this was the info I been searching for.

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.
