Default RE: AC recharge

Recharging the A/C system is pretty straightforward if you have or are willing to purchase/rent a set of manifold gauges for R134a refrigerant. The gauges are critical to avoid under-or over-filling the system.

yea if you only use the one gauge that comes with the so-called kits it is very inaccurate and you will probably end up filling it up to the wrong amount of refrigerant. it would actually be less expensive and easier to take it to a car place and have them do their 20 dollar a/c check. a/c recharge should be included, plus theyll check for leaks and make sure your a/c components are working optimally.

Check that your heater water valve is closing fully when you move the dash lever to full cold. This valve is located on the firewall behind the engine. If the valve isn't fully closed, the heater will fight the A/C and you won't get cold air.

Also check that the condenser fan runs. Assuming the readings of both pressures indicate that more refrigerant is needed, add only plain R-134a, not any sort of "sealer" or "conditioner" additive. You could add some UV dye if it doesn't have it already to help finding any leaks.

Ok, I just bought a 95 Ex and a small can of R-134, I tried refilling my refrigerant and it seemed like it wouldnt and/or couldnt take anymore. Yes the car was on and set to MAX A/C and there was contact between the can and the low side of the line. But in the end the can was still full and no cold air. Althoug illegal I also drained the high and low sides with a small screw driver and hardly anything hissed out. any ideas as to what could be the issue?

Those kits are, at best, crap. The cheesy plastic connector on the hose may not have been mating with the fitting on your car properly. For $100 or less you can buy a real gauge manifold set and a can tapper.

The basic "gas and go" is only able to "fix" (temporarily) those cases where the compressor still engages when the A/C button is activated. If the compressor doesn't engage, the system may be absolutely empty (from a major leak that needs to be repaired) or there is another problem that doesn't even involve the refrigerant.

I agree with everything mk said. In addition, did you check whether the A/C compressor belt is tight and turns the compressor when the engine is running? Does the A/C light turn ON when you push the button?
