There's a problem with the ventilation fan switch circuitry, perhaps?
The fan is turning too slow?

07 Saturn vue. My ac isn't blowing cold and my controller for the blower doesn't always work on the selected speed setting but comes on later.


Could be the AC needs recharging. Low pressure causes all sorts of things. Get an agent/shop to check and recharge if necc.

AC NOT WORKING PROPERLY


You've got some of the picture, but not all of it.
You need to know what the high and low side readings are, so yes you do need the gauge set. If the system is charged, and the low side is not dropping below 25psi, I would guess the low side pressure switch is faulty. But if the low side is dropping below 20psi when the compressor stops, the system may be low on freon. Which means you have a leak somewhere.
The hissing noise is freon flowing thru the system which could also indicate a low charge.

99 accent stopped blowing cold air


HELLO
THE 1ST THING THAT MUST BE DONE HERE IS TO HAVE THE AC SYSTEM HOOKED UP TO A SPECIAL AC PRESSURE GAUGE SET TO SEE IF THE SYSTEM IS LOW ON CHARGE DUE TO A REFRIDGERANT LEAK. THAT IS THE MOST COMMON CAUSE OF NO COOLING IN ANY CAR OR TRUCK NO MATTER THE MAKE OR MODEL

How to recharge ac on 2003 s-type


Hello AC is a little tricky when it comes to Jaguar cars as it has a certain system to charge the AC. If the problem is only low on AC gas , you have to pressure test the gas circulation to make sure that there is no leak , as recharging will not do the trick if it is a leak problem. If it is a matter of short on gas and pressure test proves that there are no leaks , then all what you have to do is connect the gas supply to the inlet gas pipe and charge slowly and on phases , while engine is running and AC is at low speed. You have to feed the gas at more than one time and close as Jaguar would not take the gas at once , it has to be done more than once at small portions so that it will take the gas. It is tricky as you have to know about AC pressure values , as if you put less that required AC would not cool properly , and if too much Compressor will disconnect and would not run properly Hope that helps

A/c blows hot


Your car is low on refrigerant.
  1. Your system requires R-134A refrigerant which is available at most auto parts stores.
  2. You will also need a hose to connect the refrigerant to the AC system.
  3. You will need to locate the low side AC fitting (looks like a nipple)
  4. With the car running and the AC turned on high, attach the hose to the AC fitting,
  5. attach a can of refrigerant to the other end of the hose.
  6. Turn the screw on the hose to puncture the top of the refrigerant.
  7. Move the can back and forth until the refrigerant is empty.
  8. Detach the hose from the AC system.
Check to see if frost forms on the AC lines under the hood and cool air blowing from the vents inside. If the air isn't cold enough, add another can of refrigerant.
CAUTION: Do not overfill the system. If the system doesn't "**** in" the refrigerant, the compressor needs resetting (disconnect battery 5 min in GM cars and trucks)
I hope this solves your AC issue. All the best!

AC STOPPED BLOWING COLD; ONLY BLOWS ON MAX MANUAL SETTING


Your AC is low on refrigerant; The AC compressor needs a minimum amount of regrigerant to run. If and when it does run (while low on refrigerant) the air coming out of the vents will not be cold. The refrigerant you require is R-134A and is available over the counter but if you are the least bit unsure as to how to add refrigerant, taking it to a garage that does AC recharging would be your best play. If you want to try to add refrigerant on your own you will need the following, 1LB can of R-134A, an AC hose adapter to deliver the refrigerant, and preferably an AC pressure guage to ensure you are not overfilling the AC line which will damage the system.
