A/C blows hot air?

The high pressure drops 3 to 4 psi from the 125psi mark. The pressure never reaches the 150 psi on the gauges. The pressure drops when the compressor is jumpered on which the pressure should increase instead of decreasing when jumpered on. The compressor has been replaced with a new pressure switch, compressor and the expansion valve has been replaced also. I would agree there must be a blockage but am having a hard time finding it. I have pulled the lines and blew through them and they appear to be ok with sufficent airflow through them. The condensor was replaced when the car was repaired. Any other suggestions would be greatly appreciated.

I have warm air blowing out of the two left vents and cold air blowing out of two right vents. This car does NOT have dual climate control!

On my camry the AC works sometimes, which seems to be weird to me?

At the beggining of the summer the ac stopped working, it would come on and off as you were going down the road(meaning it would get cold after driving for a little while SOMETIMES). Well we found out the ac hose had a leak in it. We fixed that and in doing so had to recover all of the freon in the car. (My husband has his license and does this all the time so we were able to do this at home.) After that the a/c was cold again, but it was only it's coldes in the back seat and on the right side of the car. Well we dealt with it this way for a few weeks maybe a month and then (knowing we didnt refill the car with enough freon) we added what we needed to to make it the correct amt that this car calls for. When we did that the clutch stopped spinning. We let some pressure out of the low side and the ac came back on. After that we just left it again and dealt with it like it was. Well then there was another small leak at the fitting on the high side because the o ring broke. When we went to fix it we tested the pressure added a little freon and it blew cold for a while. Well being dumb we added freon bc thats why we thought it was blowing hard or cold on teh left side of the car. THis caused the clutch to stop spinning, we let some pressure out of the high side it came on and now the a/c is hot. We finally realized or found out ot change the air filter and thats when it started blowing hard like it is suppose to, but the air is still not cold. As of right now we can put freon in, the cutch will engage and everythign seems to be working correctly but the air is hot and for some reason the pressure is hihg on the high side and low or none at all on the low side. I"m scared it's the compressor bc we always have that kind of luck, worse case senario kind of luck. Please help me figure this oout and I'll be forever thankful!

Where is the receiver dryer?

When I come to a stop, it doesn't work. Also when the weather is sunny it doesn't work, it blows hot air. But when the weather is cool (at night or early morning) it works.

Thanks, but my AC, when turned on, takes time to circulate. In fact it takes time to get to the back seat.

Okay, I will do as requested and get back to you with the results.
Thanks

The AC will sometimes work for a couple mins but then stops blowing cool air. When it starts doing the warm air, it will be stuck like that sometimes for a couple weeks. Occasionally I will try it and it will do cold air again for a few mins but then back to warm air again. I did have the Freon recharged last summer and it was cold again for one or two days but then went back to the same pattern as mentioned before. The AC light does not blink (like I have seen others describe) the AC light stays on. Any thoughts?
