Ltz Mirrors A Direct Swap?

[Jameson]

Im wondering if I buy a set of mirrors off an LTZ will they match up directly with my 1LT truck? I mean i know it will bolt up, but I mean power wise. I really want the powerfold, curb tilt, and turn signal options. Do i have to wire it or is there aplug or something already waiting there for me, like the DIC was?

GMT800 or GMT900? The 900 has in some cases has to have a different door module & a BCM program. You might try a search for more info.

I'm interested in this also. I really wish I had the power folding mirrors. Has anyone ever done this mod?

[NeverRest]

I see you posting every single day about wanting to upgrade your LT1, Christ. Lol you should have just bought the LTZ, the price differance isn't all that much. Besides once you change everything you will have went to more trouble doing it anyways.

Yeah I know, at first I was thinking to myself, I only need 4x4 and a V8. Now I want 4x4, big V8, and loaded truck. GRRRRRRRRRRR Ill be ok though, Ill have more fun adding what I want. LOL.

Subject: Swapping Outside Rearview Mirrors RPOs DL8 / DL3 / DPN - keywords rear power folding camper change door body out side #PIT4417B - (08/31/2007)

 

 

 

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.

I have a 2007 SLE GMC Sierra GMT 900 and I want to swap my regular power exterior mirrors (non signal) for the camper tow mirrors but the only tow mirrors that I've found on ebay (much cheaper than the dealer) are power, signal mirrors. Will power, signal camper tow mirrors from an SLT work on an SLE model or are the plugs different? Thanks.
