Yes it does
Expert:  MASTER TECH replied 1 year ago.
ok then if you have a volt meter I need to you measure the voltage at the single wire at the ac compressor. also do you have access to a set of ac gauges ? would like to see what the pressure is at static and in operation.it's sounding like the system might be low or a clutch or relay issue.
Customer: replied 1 year ago.
There is a blue wire on the compressor that connects to the fan I think , once I disconnect those two the condenser fan turns on and if I do connect them the compressor turns on for about two seconds and then turns off. I checked all the relays and everything is ok
Expert:  MASTER TECH replied 1 year ago.
