trying to figure out whats wrong with my ac

[madforce10]

ok last summer my ac worked perfectly and since its starting to get hot down here in florida again i turned it on full blast and nothing. not temp change at all from just vent. i took a look under the hood and my compressor is turning no air gaps at all. so im kinda stumped as it is since this is the first time having this problem. normally there is a leak some where but i know thats not the problem. and yes the temp knob was turned all the way to cool.

I'm not sure what you mean by "no air gaps" on the compressor. Is the compressor clutch engaging or is it just the pulley turning?

Probably just needs a charge. Autozone/O'Reilly's/etc sell recharge kits for around $30. Start with that. The compressor will not engage if the freon level is too low. Fill it and go from there.

X2 thats the best approach, some of the kits will have dye in them too, I got my kit at Nappa for around $50 came with the attachment to fill and 2 cans of freon, worked great.

Where in Florida are you? I have a vaccum pump, guages. and charging kit. If you're around the Tampa Bay area I can help you with it.

The Nappa kit comes with the gauge, if its hot enough out just turn on the A/C to max and charge it up, its nice to have a temp gauge inn the car to see what its blowing at, mine I think we got down to 30-40 degrees blowing, so it worked out perfectly.

The pressure guage in the charging kits is not the same as a hi/low pressure and vaccum a/c guages. If you have lost most or all of your freon the best thing to do is to completely vaccum the system to get any moisture and air out of it. Then wait a little bit to see if it holds the vaccum. If it does then go ahead and charge it up. If not get the freon with the dye like ssms5411 said to find the leak.

ok the compressor pulley is fully engaged ant the compressor is turning. it kicks in when i turn on the ac and will not kick out at all so i know i don't need a charge. im just not feeling any temp change in the air ducts.

Re: trying to figure out whats wrong with my ac

You can still be low on freon and have the compressor kick on. You just may not be low enough for the low pressure switch to trip.

Re: trying to figure out whats wrong with my ac

that can be true. ill have to take the time tomorrow to see what the pressure it reading.

Probably just low on refrigerant. When mine was low last summer it would still engage the compressor, just no cold air.

yup it needed a can. luckly i had a can laying around the house so i just put it in. the guadge was reading 25 psi and now it reads close to 45psi and is blowing nice and cool like it did last summer.
