Bad Air Conditioning

Ok those of you good with diagnosing bad AC.... It blows air, but warm. It cycles on and off constantly and squeaks badly. My dad thinks its a bad compressor or clutch in it, i'm open to any and all opinions before i start buying parts.

Sounds like a clutch but you don't want to just throw money at either. Maybe a clutch and a recharge. Mine needed a clutch and it fixed it, similar issue as you.

I recharged it. Was cold for a bit, but only lasted a few days. I'm tempted to just go to Rock Auto and get a Motorcraft Compressor with clutch and throw it in there. But don't want to spend the extra $ if i don't have to.

Same thing happened to me. It was cold but eventually it started throwing reg air (not cold but not hot either) I then took my car to two shops that work on acs and said that it was low on freon so I got it recharged and one month later I'm back to hot. Mine made a weird noise but not a squeak and it would also cycle on and off. I bit the bullet and got a new compressor and accumulator and it's been working great. I know I don't have to tell you this but make sure you put the correct amount I think it's 2lbs 2 ounces but mines a V6 so idk

Also I didn't get oem cause I couldn't afford it but I did get the parts new from O'Reilly for 350ish (compressor, accumulator, R134A, oil for compressor and some random stuff)

Also the first setting that you had that blew hot air (no squeak) is just out side air (vent)

Yea i know that, idk why i had it on that setting. It blows warm air on the Max AC setting also. And if its going to cost me $350 i would rather just pay $20 for a delete kit and save 35 pounds off the nose of the car.

Lol
You can't live where you live without air conditioning.
There must be a leak and if the system was at 0 pressure, it may need to be evacuated to be able to refill it again with Freon properly.
This sounds strange but I have my A/C work done by Thermo King. They're the company that makes many of the refrigeration units on semi truck trailers. There are dealers spread out everywhere and that's all they do is work on A/C units... Big ones! They'll do cars as well and, where I used to live, they beat everyone else's prices.
There must be one near Sac. Give them a call.

If you charged it and it was cold and then got warm again, that is a leak. I believe you can put a colored charge into the system that will be purple and it should stain the hose or fitting around where your leak is.

Could be the compressor though, or an O-ring in the system somewhere. Now would be a good time for all new o-rings plus a full vac/charge. FYI if it has leaked out already you have air in the system so you'll have to have it professionally serviced to put a vacuum on the system before filling.

Ok, when it comes to A/C i'm a complete novice so i just want to make sure i get it right......

I'll start with the colored dye to find the leak. Then if there is one i'll replace all O rings and such, is this a good kit?

Then after that hope that it isn't the compressor after all? If it is the compressor what parts would i need in addition?

I just don't want to be buying parts left and right. If it ends up costing a lot i'd rather just delete it and save 30 something pounds off the nose of the car. I've been running with it like this for well over a year so i'm used to it at this point.

Unless you have a blown line somewhere or your condenser took a hit... just o-rings first and then see what happens. If you do wind up having to replace the compressor you just replace it and have the system purged/charged and that's really it.

Ok so a bit more digging and i found this. It sounds like the guy has the same problem as me. So it sounds like a leak afterall since the system has zero pressure. I'll check it out with the dye stuff and find out where it is.

Who has replaced A/C O-rings, common places for R134 to leak from? | Mustang Forums at StangNet

If its at zero then you need a vacuum pump to evacuate the system

Yea I'll find the leak and fix it hoping it's an O-ring. Then I'll just take it to a place to get evacuated and then recharged...... Unless you've got one lol
