AC only blows hot air. Fuses are good All suggestions appreciated....Thanks

 

Is AC compressor clutch engaging?

 

Do you have freon?

 

Sounds like another Duovalve failure.
MOST complaints of a Crossfire (and many Mercedes) blowing hot air with hte A/C on are not A/C failures, they are duovalve failure. The duovalve is the gate thru which hot water flows to the heater cores. Unenergized = full flow and hot air. SOmehow, they tend to stick OPEN not closed.


Watch the video:

 

To make myself clear, A/C blowing untreated air is an A/C failure. A/C blowing HOT air is most often a duovalve stuck open. If the air just untreated, outside temperature air or is it HOT? Does turning the temperature wheels have NO effect? If so, it's the damn duovalve.

 

It is a 'failsafe' that the valves are open when coils are de-energized.

 

Thanks to all who offered valuable information. I'll be looking all of the possibilities.
