Door locks, radio, pwr seats, trunk release inop on 2000 buick park avenue

Doesn't have a fuse for power seats . Use's a circuit breaker , 25 amp circuit breaker PWR SEAT located in rear fuse box . This rear fuse box is under the back seat . Did you look under the seat to see if something is blocking the seat tracks ? Does the vehicle have memory seats ?

I would put it in the trunk. That way you'll have access to change the discs easily.

Check your fuse panel for a blown fues if there is one blown and it keeps blowing after replacing check for a broken or pinched wire especially in the door jam

Did the problem come on suddenly or was some previous action or work done......

Through the access hole in the trunk just behind the seat back on the passenger side. http://parts.nalleygmc.com/

best thing to do is take your back seats out and reach in with a coat hanger and get them....good lock...hope this helps you???????

There should be a trunk release switch in the vicinity of the driver seat. There also may be a manual trunk release somewhere in the back seat area. Also, you may be able to remove or fold down the rear seat thereby giving you access to the trunk.

Sounds like a bad ground wire or connection, as these are on different fuses.

some relays are in the fuse panel and some are under the hood in a box.

Relays are used when high current is involved. seats and windows use relays as well as fuses. Your owner manual should say where the underhood relays are. Or call your dealer service department.

check the glove box & the drivers side kick panel there should be another fuse panel located in one of these places. use a test light to test fuses
