So I tried 2 "know good" klima relays and 2 push buttons.
Then did every voltage, alternating current, ohoms and RPM tests in the book.
Did some deeper digging, removed the connector for the evaporator sensor. I was not sure what way the 2 pin thing worked so if its bad I just unplugged it. Nope, still no A/C clutch. I jumped it, still no good.
Now I'm getting real worried that something rotten may be going on with the EDS - electronic diesel computer.
I take a shot and buy a new Klima relay... It WORKS!
