I have a 2000 Bonneville SE that is having some electrical issues. The dash, buttons on the radio, and buttons on the climate control do not work. I'm assuming that these are all controlled on the same circut. We have replaced the dimmer switch and gauge cluster and that has not solved the problem. The red backlight works on the buttons on the steering wheel and on the doors. Any ideas?

There is an Int Lp fuse in the rear fuse box, as well as an interior lamp relay.

I checked both of them and they are working fine. It seems to be intermittent, I got the lights to come back on for about two days after messing with that fuse (it looked to be in crooked), but last night for no apparent reason they stopped working again. I wiggled the fuse around for a while and couldnt get them to come back on. When I take the fuse out all together the curtosey lights all go out like they should, so the problem isnt at the fuse. Not really sure where else to look at this point.

That lighting is controlled by the dash integration module. There are several splices and connectors that connect the system together. It may take some wire tracing to find the problem.
