Tryn to locate the fuse box on a 1990 Pontiac Bonneville

As far as the turn signal, did you check the proper fuse for voltage. Even if the fuse is good, if no voltage, the circuit is still dead. The turn fuse goes hot with key on, turn on the key, check fuse circuit for voltage, use a test lite or something. I hope you can read diagram?

under the hood in the main fuse box ........... there should be a diagram on the inside of the cover showing which is which .

Your fuse box is located on the driver side under the dash board. Up above where your brake and gas pedal are located. There should be a plastic cover that can be snapped off to reveal all of your fuses and on the inside of this plastic cover there should be a diagram of the fuses that are in use.

Under the hood fuse box left side (driver side)

Hi! There are 2 fuse blocks on this vehicle. One is under the hood and the other is under the rear seat. The main one you are referring to is under the rear seat. I have enclosed pictures for you. Hope this helps!

There is another fuse box under the back seat that has the fuse for the interior lights. I have the same problem. I keep replacing fuses but they keep blowing. I don't know what to do.
