a/c NOT BLOWING COLD AIR, JUST AIR...

I change the expansion valve, and recharge the system, but it still not blowing cold air. The compresor is working good. What it could be?

Are you certain that your a/c compressor clutch is engaging? You should check for any restriction in your condenser and check if the auxiliary fan is still functioning well.

The Compresor is engaging, The Fan As well, but I think is one the switch like the high and Low Switch. But I am not sure.

I suggest that you take your vechile to a certified A/C technician to clean your HVAC system and to check for any leaks.

An a/c system with insufficient cool air may have one, or more of, these problems;
* low refrigerant charge; check system for leaks
* slipping compressor clutch
* loose drive belt
* clogged condensor
* clogged evaporator
* defective evaporator control valve
* faulty expansion valve
* faulty fixed orifice tube
* clogged receiver-drier screen
* clogged accumulator-drier filter
* moisture or air in system
* refrigerant overcharge
* blend door out of adjustment
May also check the a/c relay and the a/c compressor clutch engagement; wiring, any in-line fuse - to make sure the compressor is working.

Thanks, Hopefully I can find what is the problem, I am not A pro in A/C but I try to trouble shoot some basic stuff like, check the compresor if is engaging, cheking the fan, also check the Refrigerant Level, I switch the expansion valve too. But I havent find what is the main problem, I think I have to take it to a Certified A/C Mechanic and see how much would charge me to fix it. :(
