Hey guys, new guy here looking for some help. My girlfriend'* got a 94 Bonneville and her driver'* side mirror got taken off a while back in a parking lot and I'm trying to get a new one for her. Luckily my local junkyard is loaded with Bonnevilles so it hasn't been hard to find a replacement mirror but I can't figure out how to get the mirror off for the life of me. On my Grand Prix you take the door panel off and it'* three simple bolts staring you right in the face. I got the door panel off a Bonne in the yard and I saw no way to get to the area behind the mirror without removing the whole window and lock assembly on the door, space was tight so I didn't even try. How do I get the mirror off these cars?!

Nobody'* taken the mirrors off these cars? Just looking for a few tips so I'm not dismantling the whole door next time I'm at the junkyard.

Its possible.. Should be a 10mm bolt. The bolts are tight but can be taken out.. I used a ratchet wrench. Roll the window down for the one that seems impossible to get to. The window doesn't have to be removed. Other than that your doing what we all had to do.

When your done you will feel like you can read braille.

From what I've seen on service manual diagrams there should be access holes, is that correct? Also this is a junkyard car, windows are up and they're not going anywhere lol. Hopefully it'* not necessary to get one down.

I just replaced mine moments ago. 94 Bonny but should be the same as yours. There are two 10mm nuts holding it on. Once you got the door panel off and all the wiring connectors disconnected. It helps to have the window mechanism plate loosened, but nothing needs to be disconnected other than the 10mm nuts holding the plate onto the door. Now it is a reach up into the door. The front nut of the mirror is easy. A 10mm socket and extension will do. The rear is tough. You can get a socket on it but glass from the window prevents an extension or universal from being used. I found a 10mm flare nut wrench that the head swivels to do the trick. I bought it at Auto Zone. A 10mm box wrench doesn't have the right angle to work.

Some postscrpts; I did it with the window UP. I doubt that it can be done with the window down. I also removed the front window slide. I think this was attached to the window mechanism. Be careful that it is aligned on the leading edge of the window when putting things back together. The leading edge glass is what makes access to that rear stud of the mirror difficult.
