Mirror Question

Storm Grey · July 24, 2007

Does anyone know how to get the part number for the passengers side mirror (glass only) on my 2004 duramax? It is the standard looking mirror(not the tall one). It has the accordian looking boot that extends out. I am hoping I can order a new one from gmpartsdirect.com and need the part number. The mirror does have the turn signal in it but it does not appear to be heated. Any help would be great!

what model is the truck?

bobcat5544 · July 24, 2007

This is the part # I show for the mirror 88980582

Is that part easy to install? Is it just the glass and the back plate? Is there any special tools required to install?

Is there any way to be sure that is the correct part?

The truck is a 2004 2500HD LS Duramax. Would the VIN help at all?

The VIN would help.you can post it here or send it to me in a personal message

Along the same lines, how does the autodimming drivers side mirror work? Mine now has "dual" images (like one was seeing things) at night so something is broken. This is a 2002 Sierra Denali. The mirror has the parking light down at the bottom... How do you replace just the mirror? Or do I have to replace the whole thing? Any special tools required?

Also, I put a new alternator in and while it is clearly charging there is a flashing red battery symbol on the message center. I hooked up the actron code scanner and no code. Batt indicator has not gone away even after 20 or so starts... Any ideas?

Thx

How the auto mirror dim works.

Mirrors -- Outside Automatic Day/Night Feature

The automatic day/night feature of the driver outside rearview mirror is controlled by the inside rearview mirror. The inside rearview mirror supplies a signal and a low reference to the driver outside rearview mirror. The voltage on the signal circuit of the driver outside rearview mirror varies between 0.5 to 1.5 volts depending on light conditions present at the inside rearview mirror. At night, with the automatic day-night feature enabled, the driver outside rearview mirror will automatically darken with the inside rearview mirror to reduce the glare from the headlamps from behind. The voltage on the signal circuit of the driver outside rearview mirror will be near 1.5 volts. In the daytime, the mirrors are in a normal state. The voltage on the signal circuit of the driver outside rearview mirror may be less than or near 0.5 volts. Refer to Inside Rearview Mirror Description and Operation in Stationary Windows for further description and operation of the inside rearview mirror.

Removal

1. Adjust mirror face as shown in picture to obtain access to mirror face retention clips (1).

2. Position a flat-bladed tool between back side of mirror face and the adjuster mechanism as shown in picture.

3. With a twisting motion of the flat bladed tool, separate the mirror face from the adjuster mechanism by releasing the mirror face retention clips (1).

4. With mirror face in hand, disconnect the electrical connectors.

5. Remove the mirror face from the mirror housing.

6. Inspect the adjuster mechanism for damage.

Install

1. Inspect the components for any damage. Ensure that the mirror face has all the retention clips in place.

2. Plug in the electrical connectors to the back of the mirror.

3. Align the mirror face retention clips with the adjuster mechanism.

4. Gently press the mirror back into the adjuster mechanism with the palm of the hand on the center of the glass until it locks into place.

5. Inspect the operation of the mirror.

Far as the Battery Light coming on...Is the battery installed in your truck say AC Delco on top with a black sticker.

Thanx for the quick response - does the "dual" image problem ring a bell? At first I thought my eyes were going, but it's there in the daylight and at night. I had thought that perhaps there was some sort of dimming fluid that leaked out. So this can be checked/replaced w/o having to remove the whole thing from the door - did I read that right?

On the alt issue, the factory battery went about a year ago and I replaced it with an Exide. It's a weird problem - I would have thought the computer would "see" everything is OK and reset.

Thx
