The air conditioning is only blowing hot air. It started intermittently blowing hot/cool and now only blows hot air. I have checked all the fuses in the dash and the fuses/relays in the engine. The compressor is cooling. Is there a switch of sort that switches from ac to heat? I am thinking this is likely the problem. If this is the problem how do I get at the part to make repairs.

Start by checking the pressure with a manifold gauge could be low on freon.
