Where is the door lock unlock relay located on a 1992 Buick Park Avenue ultra?
Right side of dash...remove the kick panel and the fuse block is up in the dash.
it is under the hood on the fender wall on the right side close to the windshield there is a black cover over it so you will have to take the cover off first. Hey, I'm also having problems with my fuel pump relay, and i know where the relay center is located under the hood. I just don't know which relay is related with the fuel pump. Do you happen to have anymore advice…
The fuse/relay box is under the hood on the passengers side. The box is located between the battery and the firewall. I recently had to replace the same relay after my headlamps stop working on low beam. This relay is located in the number 11 slot. I understand this is a common problem on the Buick Lacrosse. Hope this helps.
