AC not working when fan speed increases
 

My 2003 Protege5 is having AC problems.

With fan on "1" the AC and blower work. AC light is on, compressor is working, and air is cold. Fan blows slowly.

Moving fan speed to 2+ the blower works (fan increases speed) but AC stops working (AC light goes out, compressor shuts off). Cycling the AC button does nothing.

Dropping fan speed back to "1" causes the AC light comes back on and all works fine as long as fan is on "1". Unfortunately, this low of fan speed doesn't cool the car well in 97 degree summer.

PS: Replacing the blower motor resistor didn't solve anything. Did that based on bum advice.

Thanks in advance.
