Default Ac problem continues
Heater control wasn't working due to blown fuse. Narrowed it down to the pressure transducer (switch on the smaller of the ac lines). Changed it and fuse didn't blow. After a bit I tried getting the ac to work. Was adding refrigerant and fuse blew. Tried another fuse with the same result. If I unplug the transducer everything except the ac works and fuse doesn't blow. Anyone have any idea where I go from here?

Does the coolant fan come on before the (AC) Fuse blows?

Fuse blows as soon as I change control panel setting to any position other than off.

Its virtually certain you have a short in the power feed to the compressor.
