SOURCE: Recharge Auto air conditioner

I just did this for my 1994 Camry. Does your camry use the R-134A modern refrigerant? Probably.

Go to an auto parts store and buy a can of R-134A with a pressure guage included. You'll need that guage so you don't overfill the system. I bought one that allows me to save the guage and buy cheaper refills int he future.

There are two AC valves. A small one, located in the left-rear of the engine compartment, behind the strut tower, just in front of where the passenger seat is located. It might have a cap on it marked "L". This is the "Low" port, and is the one you want. The larger "H" port is up near the battery, is bigger, and is the "high" port. You don't want to use that one, and besides, it won't fit the can anyway.

Locate that low valve in the left-rear of the compartment. Take the cap off (if one is still on there). Start the engine and get it up to running temp. Turn on your AC to maximum cool, fan at maximum. Follow the directions on the can. It's pretty simple.

You'll pull back on the bushing on the refill line, and then snap it onto the valve just like you'd find on an air hose. Snap it into place, and then start refilling. Make sure the can is upside down and that you rotate and shake the can to get the coolant out effectively.

It sounds to me like your compressor got killed. What probably happened is that the airbag got a hole or tiny crack in it so the compressor has to work extra hard because it is like blowing up a balloon with a hole in it. Therefor the airbag killed the compressor. I would recommend going to and taking a look at our conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. I added the link below so you can check it out.

I hope I was of some help
Good Luck!!!

SOURCE: i want to recharge the air conditioner on a 1992 crown vic

find your evaporator inlet outlet lines on the fire wall usually near heater core inlet outlet lines. then follow both lines until you find the one that goes to the compressor. that is your low side and the port should be on there

SOURCE: Heater in mercury marquis doesn't come on. Cold

Hello. The most common cause for no heat is the thermostat. This is a quick and easy repair. Go to any autozone or similar parts store for the part. They may even install it for you.

The best answer that you can get depends on how mechanically inclined you are and how bad your problem is on the car.

If you are lucky, you can buy a A/C gauge and minimum hoses and refill the system at the low pressure fill back by the firewall around the black oblong tank with the hoses on it. You follow the instructions and add Freon until you get a steady pressure in the correct temperature range. Too much is as bad as too little. On Fords, I have replaced the Low pressure switch first and been alright with the remaining the system.

If you are not lucky, you may have to add oil to quiet a noisy compressor or you may have a bad electric clutch or leaking hose or component. There is a neat ultraviolet kit with leak detector, uv penlight, and enough juice to do 4 tests. It is available at Autozone. But you still have to fix the problem when you find it.

If your system is open, degassed, and you have to refill it you can rent a Vacuum motor to prime the system , you can do it at Autozone. It takes a significant deposit for the machine and then you get a full refund when you return the machine. Oreillys may have one too.

If you have friends or coworkers, they can tell you about the bad or good places for this service. It is really an unknown. About all you can look at is the Labor cost per hour. Good Luck

How do i find the low-side air conditioner for freon application?

Follow the a/c lines, from the condenser in front of the radiator, until you find one or both of the hose connections and the one that the a/c recharge hose fits onto is the low side port. The recharge hose will not fit the high side port.
