You can buy an inexpensive fill kit with a gauge on it. It hooks to the "LOW" pressure side of the system (grey cap near the dash on the passenger side) if you look just about where the fender well is under the hood, you can see another smaller grey cap. This is the high side. There is a little window there that if you see bubbles in it, it needs Freon. Hope this helps.

I just fixed mine. My compressor clutch would not engage. The fuse under the dash checked as ok and the freon was fully charged. My compressor clutch wasn't froze, it just wouldn't come on. If this is the case for you, there is a fuse box under your hood, which contains an A/C relay switch. it is the first rectangular block to the left (looking towards your windshield). Mine was white in color. It's about 1" by 1/2" rectangular shape.
Autozone had this part in stock and it cost $27.99 . It was black in color...
Good luck!

I had the same problem with my '03 corolla. If your freon is ok, your fuse under dash is ok but your clutch is not engaging... My culprit was a $27.99 A/C Relay switch, located in the fuse box under the hood. It was either that, or paying $75 just to have it diagnosed, then $x to repair.
Good luck!

A lot of your local parts stores sale a hand held device that you pull the trigger on with it hooked to you ac line and it will tell you if it is low or ok or over charged. It comes with a can of R134 and I think it was around $40 but it is well worth it so you don't over fill andlock up your AC pump

Only way to tell if A/C Evaporator Core Orifice tube is plugged is by looking at A/C gauge readings , An if it is plugged you more then likely need a new compressor , they become plugged with metal particles from worn out compressor. Your best bet would be to take your vehicle to a qualified repair shop .

When i turn on my air conditioner in my 1999 durango it blows out hot air. can i put in antifreeze myself or do i need to take to the dealership?


Antifreeze is only for the radiator, does not affect the air conditioner, make sure you have the setting on cold, if it is still hot than take it to your local air conditioner re gas station, most auto electricians do it, dealerships usually send them out which you end up paying extra for!!! You just need a re gas in your air conditioner.

Air conditioner blowing hot air on 2002 monte carlo and it has freon in it


car air conditioner blowing hot air is cause by either a leak or a clogged condenser, since it has a freon in it then it might be a case of clogged condenser but this is just a contributing factor, it is possible that the leak is small that you wont even notice that the freon is not enough for the a/c to blow cold air.

You need to check your freon level. Go to your auto parts store and pick up a can of freon with a gauge and follow the directions on the can.

Air conditioner blows hot air fully charged with


compressor or receiver/dryer or condensor may need to be replaced. Further testing will have to be done. Look into your sight glass and see if there is any bubbles in the glass, or if glass is extremely foggy. If so, you may have air in the system. Check to make sure you are getting power to the compressor.
