1993 Buick Lesabre: horn does not work

Resolved Question:

I need to know the location(s) of the fuses for a 1993 Buick Lesabre (CU90). The electronic button to have the seat position go back is not working. The horn does not work either. We have been told that we need to replace some fuses.

Hello and welcome to Just, Super mechanic here. About your vehicle.


The horn problem nay be a fuse, however, you might want to check the relay as well.


Here is a diagram of the horn circuit and a location for the horn relay. The seat problem is either a wire or the seat switch and or motor.
