I have the same question. Do you have any HOW TO information with pictures and procedures? I'd like to be able to make this repair myself.
The actuator is located behind the glove box. My 1995 Buick Park Avenue Ultra had this problem. It was fixed with a new actuator at a cost of $250 (price of part plus $100 lsbor)
how do you locate and repair this problem
