the best thing about owning an older vehicle is the ability to to tinker, and knowing there is an abundance of spare parts. I completed my power folding mirror upgrade in a previously thread. I now have two sets of DL3 mirrors, both of which the motor was fried. I decided to replace the motors since they aren’t that expensive. there’s ’a a YouTube video by Dan’s Garage NC fixing the mirror on his Yukon. I used that for reference. First I took the outer cover assembly off

the clips are really held together tight. I worked my way around the sides until I was able to get everything loose. This is the mirror without the backing.

Next I had to remove the mirror. The leads to the heated mirror are on there pretty good. Be careful when pulling on them. I use a small flathead screwdriver to get leverage on them.

Popping out the mirror can be a little challenging. I was worried I was going to break it, but I got it out.
Next you have to remove the power mirror motor. This is held in with 4 T-10 Torx screws.

Once the power mirror motor is out, unplug the wire and snake it thru. You can now remove the inner mirror casing. (Sorry no pic of me removing the inner casing).
Now you have full access to the power folding motor. The motor is held to the inner black plastic housing with three pins. I forgot to get a photo of that. You need a small punch and a hammer to push them thru. It's pretty straight forward. Then you remove the motor. It’s held in with 4 T-20 Torx screws. Snake all the wires through the hole of the motor and remove the motor. Then reverse everything with your new motor.

This is just the beginning. This would be the time now that I would add my cameras to the mirrors . But I have hit a bit of a snag. Drilling a hole into the housing, I will have to go through the outer and inner shell. So I have to rethink my cameras. I am going to add BSD to the Suburban. I have mirrors coming and the system from Amazon. That’s all for now.

Today I am working on the driver side mirror. An interesting note, the drivers side mirror motor is different than the passenger side.

Nice work. Please add the word "Tutorial" or "How to" to your thread's title, to let others who are experiencing a similar issue know that this thread is not a question, but rather has an identified solution.

I took that photo before removing the 4 T-10 screws. The backing plate/inner cover comes out after removing the motor.

I meant the mirror mounting cup (with 4 U-tabs) is still attached to the driver side mirror actuator motor, but missing from passenger side photo.
So I can't see the difference you mentioned.

Unless you were talking about the mirror folding motors, and not the adjustment actuators...

The repair is complete. The mirror is back together. I replace the white caps with my newly painted covers. I have another set of DL3’s If any one is interested in a set drop me a line and I’ll get you set up.

I'm about to pull mine apart and replace the motors. Picked up some of the brass spur gears from GruvenParts.com.

My driver side looks burnt. I was reading somewhere that it was the auto darkening portion that failed. Hopefully I can find a replacement glass.
