AC works only after jumping AC Comp relay

[quote=“Nevada_545, post:12, topic:184729”] compressor should operate anytime “Auto” is selected, hot or cold.

I wouldn’t have guessed that. Do you mean when “auto” is selected the compressor always turns on immediately, but turns off eventually if the air is too cold for the setting? Or does the compressor turn on and stay on indefinitely as long as “auto” is selected? Maybe I don’t understand what “auto” means. Maybe I don’t know what “the compressor turns on” means.
