Da, stupid me, problem solved. The test light wasn't grounded properly. I ended up grounding it to neg battery post. Results are: 12v current at compressor switch with ac control set to cool and blower switch
on, no current if blower off or ac control set to heat. I'm just trying to make sure everything operates correctly while truck is still blown up enough to get at everything fairly easily. After aprox 3 years I'm at this stage. Fortunately I retired last year and only work part time so my project is starting to move along quicker. Thanks for eveyones input.
