A/C not working again!!!

[Johnandcara2]

Took the coach out of storage and this was the first warm day, Turned on a/c with engine running thinking that it may take a little time to cool 75* out side set on cold and didn't get much cooler than just blowing air @the driver or pass side vent. This happened once before took to frieghtliner dealer he replaced fuse (?) , I did notice the outside fan noise (compresser ?)was not working. I was shown a black tall relay that was in outside electric bay box , but I can't remember which one. This relay was the cause of it not working before . Could it it be the same again? thank again if anyone can help. John

Was it house air or dash air. If it was dash air and it's blowing but blowing warm, it probably need a recharge. Not a big deal

With no info on the year and type it's hard to give a general answer. Hope this helps.

dash air for sure, problem is now no warranty. I don't want to spend $$$ to repair if only a fuse/relay. Anyone else have this problem?

Yes, it could be the same again.
What fuse did the dealer replace? Might be the same one again.
The outside fan is not the compressor. The compressor is on the engine and should be silent.
Depending on the coach you might have electric fans that blow over the condensor coils in the rear of the engine bay. They have a fuse but you can install a circuit breaker in the same fitting.
