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.
