I had a problem with my 86 420 SEL a couple of mos back- after having a MB reman compressor installed, my lft instrument cluster would die, and the compressor would not kick on.
All fuses were ok. I followed Benzmac's advice and replaced all of the fuses in the box- problem solved.

My mother now has the car, and calls me this morning and tells me that now the gas gauge does not work, and again, the a/c compressor is not kicking on. My mother lives 2+ hours from a dealer, and the nearest independent is 1.5 hrs away. Where do I begin? Again, all fuses are ok. Is the fuel level sending unit on the same circuit as the a/c compressor kick on?

Thanks in advance

The contact where that fuse rides has heated up over time and lost it spring. This will result in wear on the top of the fuse. You will have to replace the fuse again for now and then eventually solder in a remote fuse holder.

LOOK AT THE FUSE FOR THE GAUGES/CLIMATE.

I have had to solder an external fuse holder in my fathers rolls. The one ont he board was busted, and that part on that car is not cheap...

Follow Benzmac's advice...again. :)
