ETR switch climate control 1983 300 SD. problem
 

I have a problem with compressor not ingauging. I have traced electrial to the ETR switch and have 12V at tirminal #1 . No power to tirminal #2. If I jump across 1 to 2 the relay and compressor ingauge and A C will cool. Can you check the ETR switch adjustments ? Do not want to buy a new ETR switch if It will not fix my problem.

go buy one it will fix your problem.

Thanks for your reply. I like your tag. I was a Master Tech but am retired and sometimes have problem understanding MB problems. apriciate your input. I will try a new ETR. Thanks again.
