Well, I guess trolls need to keep cool too. If you bought the 'can with the little hose and gauge on it' at an auto parts store, I suggest you go back there and ask the friendly counterman to show you where and how to put it in. He should be happy to comply.

R-134a

Have you tried a Dodge or Neon enthusiast website, like

There's also , a site dedicated to automotive A/C and that has FAQs and forums.

I wouldn't simply recharge the system but would take it to a good general garage (look for AAA approval because AAA requires binding arbitration in case of disputes -- binding on the garage, not the consumer) or automotive A/C specialist, just in case the problem is something other than low charge. Because if you put in too much refrigerant the A/C won't cool well at all, or the pressure may become high enough to blow the relief valve or even a hose. :(

You really shouldn't be doing this without a little more knowledge of AC systems than you appear to have.

Thank you very very much larry moe n curly and you too Don. I was afraid i might have been stepping into a gay forum at first with the responses i got. They are either gay or little boys. Didn't mean to step on your toe's. Wasn't trying to come between you and your boyfriend. I came here looking for help because my husband was killed in Iraq last year. I am doing the best i can raising 2 boys 5 and 6 years old hence Sherry"56". Well anyway thanks again Don and Larry Moe n Curly greatly appreciated Sherry

I am sorry your husband was killed in Iraq.My sympathy for y'all. cuhulin

A's'shole.

Classic!

BTW, I would much rather be gay than a stupid, worthless bitch.

You have started into something that you clearly dont know shit about. And you have replied like a real bitch.

You clearly dont know enough to even start the project.

Can you describe the symptoms in more detail so that some of the experts here can help better?

Does the A/C cool at all? When you turn it on, is there a loud snap or click from the engine compartment and a momentary decrease in idle speed, indicating that the compressor clutch has engaged?

Does the radiator fan run when the A/C is turned on? If there's more than one fan, are both spinning? Some cars use a single fan that runs at two speeds, and I think it's supposed to run at high speed when the A/C is used.

If the A/C cools at all, then adding more refrigerant may solve everything. Here's how I do it without proper pressure guages, but keep in mind that it's NOT the proper way and that I'm no expert:

You'll need a 2-3 quart pan or pot, a pair of dial-type food thermometers that can read below freezing, some tape and wire, and some insulating material (sponge, cotton, rags, several layers of tissue paper).

Verify that the thermometers are accurate by holding their tips togetrher while stirring them in ice water. They should read 32F when you do this, but it's OK if they're off a bit, provided that both read identically because you'll be checking a temperature difference more than absolute temperatures. Attach the tip of one thermometer directly to one of the evaporator coil's pipes near the firewall, the other's directly to the evaporator's other pipe. It's possible that one of the pipes is located on the accumulator/dryer (silver or black vertical cylinder, about 3-5" diameter). Close the doors and windows, start the engine and turn the A/C to max and high speed. If possible, do this when the outdoor temperature is about 70-80F. Maintain a fast idle speed. The thermometers should slowly cool down, but one will probably cool down much less than the other. Add R-134a until either the two thermometers read about the same or the pressure is high enough.

The charging valve looks like a tire valve, only about twice as fat, but like a tire valve, it has a screw-on cap, probably made of black plastic. You want to charge through the low pressure (suction) charging valve, but fortunately with R-134a systems the low and high pressure valves are different sizes, making it virtually impossible to connect to the wrong one. But if you're nervous, the low pressure valve is the cooler one. It may be located inline with the suction pipe, or it may be located on the accumulator-drier (black or silver vertical cylinder, about 3-6" diameter).

I don't know if it's necessary, but I purge air out of the charging hose before attaching it to the A/C by cracking open the valve on the R-134a bottle for a second or two and letting out some of the gas while attaching the hose to the A/C fitting. But some hoses have their own valve, in which case you'll have to open the valve on the bottle and press on the hose's valve stem for 1-2 seconds with a screwdriver to let out gas.

To charge the system the bottle of R-134a has to sit upright in a container of warm (100F) water to prevent it from freezing and losing pressure, and it has to be upright so that only gaseous R-134a enters the system because liquid R-134a can slam the compressor. It can be a challenge to maintain the bottle upright, so consider rigging some kind of holder.

Charge slowly so that you don't overcharge. Turn the bottle's valve open just a little, and watch the two thermometers. If they don't drop after 30 seconds AND your pressure guage reads less than 20 PSI, crack it open a bit more. The two thermometers should read lower, and when both read almost the same cold temperature (probably 35-40F) OR the guage reads just over 21 PSI, turn the valve shut..
