07-08 Mirror Swap

[jtt454]

I got an 07.5 Sierra and have the regular powers on and was looking to go to a set with the turn signals. Will this just be plugand play or will I need to get it reprogramed for the trun signals?

Why bother? I have them in my Cadillac and they sure are

annoying at night !

 

Anyhoo........Just buy the replacement mirror glass with the

turn signals at about $50 bucks each. Not sure about the

wiring tho...............

Hello, If you install the mirrors with the turn signals only the turn signals ill work, nothing else. The wiring in the doors is different. So as long as you dont want the power fold or driver side auto dim you are ok. If you do want them it will be easier to buy a new truck. I bought the mirrors and just used the wiring and the glass and installed them in my existing housing. Was easier than trying anything else.

#PIT4417B: Swapping Outside Rearview Mirrors RPOs DL8 / DL3 / DPN - keywords rear power folding camper change door body out side - (Aug 31, 2007)

 

 

Subject: Swapping Outside Rearview Mirrors RPO's DL8/DL3/DPN

 

 

Models:

2007-2008 Chevrolet Silverado

 

2007-2008 GMC Sierra

 

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern:

Some owners may request to have a different style mirror installed on their vehicle or request a different mirror before they purchase the vehicle. The new electrical architecture for the Silverado and Sierra has made swapping of the mirrors a more involved procedure than with previous models.

 

Recommendation/Instructions:

When swapping mirrors on a vehicle, the first thing that needs to be known is if the vehicle is equipped with door modules or not. The easiest way to determine if the vehicle has door modules is to use the Tech 2 and try to communicate with the "Drivers Door Switch" and "Passenger Door Switch". If the Tech 2 can communicate with these modules then the vehicle is equipped with door modules. If the Tech 2 cannot communicate with the door switches then the vehicle does not have door modules and the wiring between the driver and passenger mirrors is hard wired. The information below will be divided into two different areas:

1. Swapping mirrors on a vehicle equipped with Door Modules, and..

2. Swapping mirrors on a vehicle NOT equipped with Door Modules.

 

Swapping mirrors on a vehicle equipped with Door Modules,

The information in this section covers three different mirrors to swap on vehicles equipped with door modules: Base Power (DL8), Power Folding (DL3) and Camper (DPN). Before any parts are installed new door module calibrations must be obtained from Techline Customer Support. Advise the Techline Consultant that the vehicle is getting different mirrors, provide the RPO of the mirrors being installed, and request a new calibration for both door modules. Also, if switching from DL3 to DPN/DL8 or vise versa new drivers door switch trim bezel will need to be obtained. Once you have the calibrations and correct bezel, then the mirror swap can be done. If the calibration or switch bezel is not available the mirror swap is not possible. Replace the drivers door switch with correct part number for the mirrors being installed from the chart below, programmed both door switches with the new calibrations from Techline and install the new mirrors.

 

Mirrors Driver Door Switch

 

DL3 15906881 4-power windows

 

DPN or DL8 15906880 4-power windows

 

One additional note to remember when swapping from DL3 to DPN or DL8. If the vehicle is equipped with memory RPO AN3, only the DL3 mirrors have memory recall. So, if the DL3 mirrors are replaced with DPN or DL8 mirrors the curb view assist and memory mirror features will be lost.

 

Swapping mirrors on a vehicle NOT equipped with Door Modules,

This information only covers two different mirrors to swap on vehicles NOT equipped with door modules: Base Power Mirror (DL8) and Camper (DPN).

 

These two mirrors can be swapped without any additional hardware changes. The only thing to be aware of is that some vehicles equipped with DL8 mirrors may not have the turn signal wiring, due to the DL8 mirror is not equipped with a turn signal indicator. If the DPN mirrors are installed the turn signal indicator may be inoperative unless the turn signal wiring is installed. Please do not contact Partech for a wiring harness, the wires will have to be added.

 

Note: The Power Folding Mirrors (DL3) are not available and can not be installed on a vehicle not equipped with Door Modules.

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

ok so what wires do we need to "add"?? I am not sure how my truck is wired though...and dont have access to one of them tools? I think all my mirrors are right now is power tilt...they are just the basic plastic turn signals...I would like to put denali mirrors on it...will this work???

[EXSlider400]

I added signal mirrors to my W/T. Just find what you want on e-bay as far as signal mirrors/colored covers/etc... They should plug right in as far as mirror functions. If the signals dont work just do what i did and wire it to the front turn signals. You can ground them to 1 of the 3 mounting bolts. The "hot" wires in the front signals are peach colored.
