Thanks for the help! I think it's fixed for now. There are 3 relays in the circuit for the compressor and blower. Two are together and work together. I took these apart, checked with a 12v supply, and found 1 not working. I freed up the moving parts, cleaned the contacts, made sure they both worked and re-installed. No more smoke so I will replace with new relays tomorrow.
