Greetings listers!
I'm having some electrical issues with the ACC2 system in our '80 300TD wagon. Hopefully someone has been down a
similar road before and can spare some insight.
The symptoms are pretty simple: fuse 3 self-destructs when the pushbutton module is in the bi-lev or auto functions, and
the compressor stops functioning. The compressor functions as normal in defrost mode, and in general, the ACC servo
functions as normal - vents open as necessary, temperare regulated just nicely. A fuse lasts maybe 2-3 trips before
blowing up. I've blown the fuse in both Auto-Hi and Bi-Level, without use of the other function until the fuse blew and
was replaced. As part of my troubleshooting, I swapped out the amplifier with a known good spare, and the symptoms
remain. I'm a pessimist, so I'm suspecting that the compressor is drawing too much current.
So, are there any obvious places I should look, and where should I begin my tests to narrow down and eventually isolate
the problem component?
