A/C not working in 1996 Chevy Cavalier

SOURCE: 1991 camaro overheating

There are two freeze out plugs at the rear of the block (V8) and many v6 engines. If coolant is coming from where you say, likely they have failed. Unfortunately, the only way to reach them is to remove engine or transmission, It's rare that they fail because they are "protected " by the bellhousing, but can still rot from the inside out. There is no sealer known to man that will fix this. It's a shame that you need to do all that work for a pair of $2.00 plugs, but that's what needs to happen.

More likely the recharge blew a o-ring and you have a leak. When your Cavalier was blowing hot air and a recharge fixed it that means it was low on freon which lets o-rings dry out, go back to the shop and have them leak test it. They use a pressurized dye to find the problem. If it's blowing it's not the cooling fan relay, they may have meant compressor relay but I'd have a leak test done first it's not expensive and easier that chasing unknown possibilities.

SOURCE: air will not blow cold after freon has been put in it

ymeadows: If you have properly re-charged your A/C system to the correct pressure and do not get cold air coming out of your cabins vents, then you have a clog somewhere in the A/C system. This may be caused by a dirty orifice tube or expansion valve (same part different name) or the clog could be in the evaporator or condenser. I would not continue to use your A/C until you locate the source of your problem as this may cause over-stressing of other critical A/C components. If you are mechanically inclined and familiar with how A/C systems work, I would start with replacing the orifice tube or expansion valve. These can be on the high or low side of the A/C system and varies from one make and model to another. PLEASE VOTE FOR THIS SOLUTION IF YOU FOUND THIS INFORMATION HELPFUL, THANKS,

That could be the case. The other problem could be that you are losing freon for some reason. Find someone who can check the freon level for you to make sure that it is not leaking. The valve to fill the freon can get bent which allows for the gas to escape and then you run into this problem.

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.
