W126 380SE A/C Inop

[gmercoleza]

My A/C was working this morning, now it's no-go.

The compressor is not engaging. It was getting dark as I pulled up to the house, so all I was able to do was check fuses and wiggle them all, ensuring they are all seated properly. I'll take a closer look tomorrow morning but figured I'd throw this thread out there to see if anyone can speak to the common trouble spots on this car (I haven't done much A/C work on it thus far other than charging).

First thing I'll do in the AM is check the charge to make sure it's not too low, but I don't expect that to be a problem.

Are there any relays or anything connected to the climate control panel that I should be checking as well?

Thanks in advance!
