I am trying to finish up my a/c diagnostic. I get no voltage from pin 10 to pin 5 of the pins on the Klima relay. Therefore, I am not getting ground signal. How should I track this down? The A/C is fully charge and blows cold when I jump pin 5 and pin 7. I know the season is getting cooler, but I want to finish this project. This is on an 86 420sel.

Thanks,

John
