[Red Devil]

Took it in to get a charge, turned the a/c knob, and nothing, no power what so ever. Flipped the knob back and forth and the blower kicked on for a sec and just shut down. Checked all the fuses and they were fine. Went ahead and pulled the switch and replaced with a new one since I had one laying around and was hoping that was it but it wasn't. I noticed that when I hooked a light tester up to the hot wire that was connected to the switch that it would come on, but when I turned the ignition on and off, I would lose power again. Pulled the relay out and disconnected it from the wires. I noticed that the red/wht and blk wire that was connected to the relay had power, but no matter what position the key, I never got a light to show the yellow and red wire had power. Don't enough about the electrical or how relays work to see if the relay is the issue. I did order one in hopes that is the issue though. Any ideas? Thanks...
