Problem just started, I have no Idea where to begin looking for the cause. I started with the basics like checking for a blown fuse. A service manual I found said there is a system module under the passenger seat. All I can find there is what appears to be a relay in a connector. Anyone have any ideas where I can start looking for the problem?

I just started having the same problem in my GS. Any ideas?

Check the yellow connection under the driver''s seat. I had the same problem with mine. If CD''s or anything else gets under there it can become loose.
