My sleeper ac not working

Place 12v fan on dash pointed to sleeper

 

Does it blow hot air? Or does it not blow air at all?

 

It's almost November. Let it ride 6 months then worry about your a/c.

 

Need more details, like @ShooterK2 mentioned above. Is the blower still running in the bunk?

 

If it's blowing hot air in the bunk but it's cold up front, I'd start looking at the control panel where the bunk temp knob is. Or possibly a fuse and/or relay that runs that panel. The fact that it's cold in the cab tells me it's got freon and the compressor is doing its job. I'm thinking it's electrical.

 

You need to replace the cab expansion valve, it's probably all clogged up. You said they replaced the AC compressor. Your compressor was probably fine. Have them drain all the R134a out, and replace the cab expansion valve and also replace the receiver drier. Receiver drier is basically a filter for the AC system. Also have them put the system under vacuum for at least an hour, longer the better.

 

Try resetting your HVAC blower sleeper fuse.
Good Luck hahaha
