The air conditioner unit did not work, so I had it serviced. Two cans of freon were put in, to no avail! I spent the whole summer in St. Louis with no A.C. Now the heater only blows out cool air! I replaced the thermostat and put in anti-freeze. It still does not work.

Did the compressor come on with the ac?

What were the exact pressures?

The blend door motor may the issue with the heater. Can you hear a clicking noise in the dash when you turn to heat?
