Toyota Repair: 1994 toyota camry ac system, toyota camry, toyota dealer

Question
I have a 1994 toyota camry 4 cylinder and my a/c blows hot air, I have replaced already the compresor and the air dryer bottle, also the a/c preasure switch is brand new from the Toyota dealer. I filled the system with freon and still blows hot air, and my compresor cluth is always on even though that I have replaced it already. Please can you help me to see what other thing can be wrong with my a/C? thank you, Juan

Answer
Juan,
You would be money and hassles ahead if you initially
took the vehicle to a good Toyota a/c technician.
Its probably something simple and there are step
by step procedures that one must go through to
resolve the problem. It could be a relay, fuse, or
valve under the dash. I would have to be at the vehicle
to find the solution.
