My t800 will only blow hot air. I've changed the acutator and the controls in the dash. Still blows only hot. Tried turning the A/C on, compressor kicks in and still hot air only. Any ideas?

Technically, the compressor won't kick on if there's not enough freon in the system. Unless it's my truck where the low pressure switch seems to be messed up.
But yeah. If it's low. There won't be any cold air. Put ac gauges on the system and see what the EQUALIZED PRESSURE reads without compressor running.truckdriver31 Thanks this. -
