Hello,

I have a 91 300SE with a problem that's really stumped me. It started all at once a couple of weeks ago. My dash lights (console and climate controls) will not come on (I did try wiggling the dimmer). The climate controls no longer work (although if I turn it on and drive it does trickle out) and the fan in front of the radiator no longer comes on. So when the car is idling or I'm stuck in traffic it heats up.

Soooo, naturally I check the fuse that controls all of those and it wasn't blown. To be sure I replaced it just in case. Then I got frustrated and wrapped wire around the terminals. Still nothing (yes, I put the fuse back in).

Sometime before they all went out my front driver side window switch went faulty. I had moved the one from the back to the front so that I could pay tolls - but since doing some research on this board I've put it back the way it's supposed to be. Unfortunately, that didn't seem to make a difference. I'm not sure if the problem started when the switch went out, but it was around that time. I somehow remember the switch a couple of weeks before the lights and fan issue.

I have no idea where to start looking now. I'm fairly good at engine/transmission things - but when it comes to the electrical my knowledge ends at installing a new stereo and rotating switches.

Any ideas? Where should I start? Could this be separate issues that started at the same time? Should I just abandon the car on the freeway, claim it as stolen and use the insurance money as a down payment on a 1937 540 K Cabriolet?

Thanks,

Brian
