Power seat on drivers side of 1996 buick park ave. wont go in reverse every ting else works ok

Why ? Go to the Auto salvage yard an get a used one for $5 or $10 buck's .

I am not sure about changing the name as my 2000 park ave. only indicates driver one or driver two. To reset the memory for seat/ mirror position is rather simple: with the ignition on and the car in park, adjust your seat and mirrors to the desired position. Then press and hold the desired button (driver one or two) until you hear a beep, This is the procedure that works on my 2000 park ave. I hope this helps you.

should have buttons on your armrest or down on the side of the seat by the drivers door if not check in front of the seat

Fron first principles, the reverse movement of the motor is caused by reversing power polarity to the motor. If he motor runs in one direction and not the other then it isthe switch. It is not conecting power to the reverse contact. Check.replace switch.

If only one seat is not working the fuse/relay is ok or both would not work, most likely cause based on experience is the control switch, then the power seat motor.

I remember replacing a lot of power window motors on Buicks,but not a lot of switches.Use a basic 12v test light to verify everything is OK to the motor.

If NONE of the functions work for the driver's seat, I would suspect a boken wire. Check the ORANGE wire on Pin "L" at the seat switch connector. This should have power at all times.

Pin "A", the BLACK wire should be ground. It grounds at G200, which is located in the left front kick panel.

If both of these wires are good and functioning properly, then you most likely have a fried seat control switch.

I think you may want to have the battery looked at first. As for that noise. you may have a automatic leveling and that would be the pump kicking on and off.

I had exactly the same problem in my 1995 park ave, it was just a fuse.

either the switch or the electric motor is rusted out inside from moisture
