AC problems?
okay its winter now but last summer i tried to use my ac and it will work sometimes and then most times it didnt work. it would just blow hot air. this is a must in my car to have. so i turned it on and pop the hood. the compressor did not engage with the belt. i dont think its the ac compressor though. is anyone else having this problem or is there someone who knows with experience about this? it be greatly appreciated.

I wouldn't recommend doing it yourself with cans, judging by system pressure isn't very accurate at all.

A/C probs have to be addressed 100% there are no short cuts. First you have to do a gauge reading. If your Low side is above 45ish and your Hi side is below 200 + ish then you have a prob. That prob is solved from starting from Point A. Bring down the system. run a vacuum test, if you lose Vac, replace all o-rings. Run Vac again, if it holds then your cool. Open system, flush, replace accumulator, vacuum and charge. If it loses Vac after O-rings are replaces CORRECTLY, your Compressor mite be leaking. Replace it. If you Charge and get screwy readings (low side hi and Hi side Hi) your Expansion valve is trashed ---replace.
Its a damn can of worms ---I tend to just bite the bullet and unless I have a compressor that is obviously oily (leaking) I open, replace accumulator (always a good thing) the Expansion valve (contaminated) Flush, Vac and Charge

And actually judging by system pressure is very accurate is you take into account ambient
