The receiver/dryer has 2 switches on it. unplugging one disabled the AC completely (black connectors). Unplugging the other (white connectors) didn't effect AC (still ran and blew cold). When I jumpered those together the auxiliary fan still didn't run.

The relay that clicks when I unplug the temperature switch on the engine is the 3rd one back on the left (black). Is that the same relay that would manage the low side? The relay power according to the paper inside the fuse box is #7 and it is good. Is it the same fuse for both high fan and AC fan?

Thanks again!
Bob
