Dealer can't figure out why my new CR9090 won't blow cold air. The compressor won't kick in, gauges show full of freon, first time I got it out of our storage building it was warm air coming out and I had the 01 code showing..dealer ordered high pressure switch and installed it with no change. Today they switched out a controller box from above right side tires behind seat , but from the outside, no luck. Then the tried the atc inside the cab switched with our other 9090 no change. The working combine will click the relay after about 3 seconds but my brand new one will not. I get no codes both on laptop and atc. Dealer left tonight scratching his head. I understand new machines have bugs to work out so no worries or impatience here, just looking for help as to what might be going on. Mechanic said he can get the clutch to engage by hot wiring it...so basically something is not telling it to turn on. Any ideas appreciated.
