Power door lock switch replacement

You can remove the back seat, and it should give you enough room to pull the inner door panel off..

see the diagram attached. test the cables, connector, for open, dirty, bad contacts. Switch, test for bad contacts, clean with contact cleaner, and finally test the motor for open or faulty.Test the fuse or . c.breaker for open or faulty, and clean contacts.
God bless you

They are not prone to fail. I always recommend to replace only major when engine repair is needed.

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.

Will the windows go up and or lock from the respective doors? Is this the master control on the driver that does not respond? If so remove the driver door panel ( see 97 Park Ave door lock for instructions ) and check the wireing harness located under the switch control panel, make sure all are pluged in well and are not damaged. If the wireing harness is in good repair You might want to check salvage yards for the appropiate control switch replacement. ( watch them remove it from the junker and you'll know how to install it )

Order the exterior door handle AND the clip that attaches the rod to the exterior handle from your local dealership ( any part in the salvage yard will have at least as much wear as the one U are replacing ) Also order a can of touch up paint matching your car. After you have the parts and have painted the new exterior handle, roll down the window and remove the interior door panel. ( instructions have been posted at 'replace door lock buttom' ) Two nuts, one on each side, hold the broken handle in place and must be removed ( DON'T loose them ). Loosen the rod from the clip at the top to allow a bit more room, But take note on the way it is attached ( you will need to reattach the rod to new handle ) To install new mechanism put the new clip on the rod, carefully place the gasket and the new handle in place and install nuts to secure. Test the door handle and make sure it works. Reinstall interior door panel.

At the bottom of the door panel you will find several screws ( haven't removed mine in a few mo. and have forgotten how many ) there are also screws under the slotted bottom of the finger grip in the door panel. After removing screws lift the panel from the bottom and to the top of the door. You will encounter clips on the rear of the door panel the most problematic is by door locking mechanism. Use a small blade flat screwdriver to Gently prise the clip out of the metal door. To pass over the interior door handle piviot the door panel, Take Care the wires for window and door lock are located here!
I used Gorilla Glue to reseat my lock button be Cautious not to bind the lock button, or the function will be impaired ( won't work ) HAVE FUN
