I would start with checking the fuses and reading out the OBD II codes. The main two fuse blocks are under the hood in front of the strut tower on the driver's side and in the trunk on the rear of the back seat.

Is there a BCM body control module in that car? Just another possibility.

There is a PZM on the 1998 STS, which is the car on Viby's profile. In fact I think there's a PZM on just about all cars sold worldwide for at least the last ten years. You can find out quickly by running the OBD codes and watching for the PZM's turn to read its codes out. Hey, were are Viby's OBD codes???

If you are using a code reader, most of them that can be had for under $200 just read the PCM codes. Use the A/C buttons to activate the self-diagnostic mode and read out the codes on your driver's message center. See the link in my signature block for instructions.

From your posts, it could be a fuse or a ground, but it's not likely a computer module. The computer modules very rarely give trouble themselves, unless you hook jumper cables up backwards or make some similar catastrophic mistake.

There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises
