Question about 1992 Pontiac Bonneville
Cant find a fuse for the power locks. Is there any thing besides a fuse that can cause it... and on the same note where are the relays located.. thanks!
Underneath the steering wheel, that plastic trim panel covers your fuse block. In that fuse block is the fuse for Power Locks, or it may be labeled ACC. (Accessories)
Yes, many things besides a blown fuse can cause the power door locks to not work.
1.Fuse Good? Yes? Go to 2.
2.Door panel off.
Door lock motor solenoid getting power? Yes? Check door lock solenoid.
(The solenoid is merely a coil of wire that moves a plunger up, or down) (You need to see if power is being fed through the wiring harness, going through the door, from the fuse block)
Check door lock solenoid with jumper wire that has power. Make sure the door lock solenoid has a good ground, and no corrosion between it's body, and where the body of it bolts to.
Water can get past the weatherstripping, make it's way into the door, and cause corrosion. The door metal, is the ground for the door lock solenoid.
Check through the rubber tube,( Going from the car body to the door), and see if there is a ground wire. Sometimes there is an additional ground wire, in the wiring harness, going through that rubber tube.
If so, check it's connection to the body of the car. Don't assume that because it looks clean, and is tight, that there is no corrosion present between it's metal spade connector end, and the body of the car.
Remove it, make sure there is a clean connection, (NO paint), and reinstall.
I suggest this for all of the connections.
