How to install trunk motor - 1991 Buick Park Avenue
I like to replace the whole unit instead of just the motor since in most cases the gear which is plastic breaks. But just take the carpet and pull it out of the way and there are three phillip screws on the left side that needs to be removed and then unplug the connector and just reverse the process. However, sometimes the diode in the module burns out and doesn't allow the trunk warning light to go out after the unit itself goes out, but if this happens you can go to the Radio Shack and get one for about $3.00 and cut the green wire at that connector and soilder it in right there and problem solved...saves buying a new module to control that and is an easy fix.
