Just to make sure I'm recharging the right thing. When I'm standing at the front of the car looking under the hood, is it the valve closest to the front of the car on the right side?
The recharge tube should only be able to fit on one.
I managed to get it onto at least 2 last time I tried. The other was on the left side of the engine bay closer to the engine bay I believe. I didn't put anything in that one though. It is the one on the right by the bumper?
That's where it is on the zetec. I imagine the Duratec is the same. If your a/c is working at all, the low pressure line (where you inject the coolant) will be cold when the system is running.
It blows but certainly not cold.
So it turns out I have a leak somewhere. I got the recharge can w/ the meter on it. It read 0 so I filled it up (w/ car and a/c on) and it went into the blue. I stopped and went back to the car, still hot air. I turned the car off, and it sounded like the compressor was still on. I went back to the front of the car only to hear a serious hissing noise and I looked at the meter and saw that it was dropping. So...off to a shop for the a/c
Anyone know about how much it'll cost to get the system checked out?
When you say...you got the recharge can...you mean you can buy a can of refridgerant? I guess thats only in the States...cause you can't do that in Canada...have to have an OZone certificate to purchase it.
Yep. You can go pick it up at any auto parts store.
If it was empty, it's going to take more than one can to fill it. However, I think you made the right decision when you decided to take it to a professional. If it's leaking, it's going to be very difficult to find it and fix it yourself. I fix most things myself on my vehicles, but I just took my Chevy truck to a mechanic for A/C repair. It's too easy to go wrong if you don't really know what's going on.

Places all over Houston (The A/C capitol of the US) that state "Free Air conditioning check up" or "Free Air conditioning inspection." How much you want to bet they find some high $$ thing needing done?
Would an empty A/C not let the compressor to turn on..?
I haven't checked mine closely yet, but when I turn on A/C it doesn't seem to even start the compressor. There certainly is no load on the engine.

Yes, every time. There is a low pressure switch that disables the AC if the freon pressure is to low. It is a protect for the compressor. Without this switch, the compressor would burnout because there'd be no oil (which is in the freon).
Thanks. Guess I'll be making a stop to buy some freon..

No you won't. You can't buy Freon (a registered trademark of the DuPont Corp) without special licensing. Besides, NO contour ever made used Freon.
Buy R-134a. It is NOT Freon.
In any event, the pressure from the the refrigerant can might be enough to close the cycling switch and engage the clutch. It takes about 45-50 psi to make the switch.

Sooo... my A/C Clutch keeps turning on and off, and giving me warm air out my vents because I have low R-134a?

Yep. That's what mine's doing (or was doing, as of tomorrow.. can't take the heat).

Same here... my A/C was somewhat strong when I first bought her... then she faded away... takes longer to get it cold then my moms escort...
Tell me how it works out
Ummm... got a can, got the hose/connector, please verify i did this correctly:
Start car
Turn A/C on
Connect the can and make sure the top valve is open (mine has a valve on top)
Let run for a few
Unplug
I think thats the right order.... cus my A/C still feels alittle warmish... not ice cold like my moms escort...
You should get a kit with a guage so you know where it's at.
Got a gauge... dont work...
You should notice that the can gets cold and lighter as the freon is sucked out. If the can stayed full the service valve may not have opened. It's best that you get the gauge to work, or test it on another car to see if it works.
Can did get colder, and lighter... but i still think not enough was added...
Hey RyeLou,
How much did you end up paying to get your leak fixed? I just discovered my roommates 98 contour, which she just got, has a leak (somewhere directly beneath the low side valve by the sound of it) and was wondering if that's gonna be a lot to fix...
Doubt he'll read this.
This is A YEAR OLD! He has sold his car.
Might be the accumulator can, they rust out. Located against the radiator on driver's side.
LOL, oh! well yeah, it does sound like it's coming from the accumulator...
Could be the condenser. On my SVT had to replace the condenser and the conderser on the 97 has a leak right now. I'll be off to the junk jard to pick up a used one for that car. I put a new one in the SVT. Both leaks were on drivers side not to far from the top.

If wanted my A/C to work all the time I'd have to recharge it every day. I'm not sure what needs to be replaced and I think I might have to flip it to a mechanic for this one...
I Figure a few people might benefit from this post as it is again A/C season!
Is 1 brand/ can of R-134 better than another? The reason I ask, I need to recharge my Tour. Targe has a can with a pressure gauge and hose (all 1 unit) for $21.99 on sale. It was sittign right next to the small R-134 plain-jane cans. I don't have access to a hose or gauge so I thought this would be a good alternative.
What are your thoughs?
They are all chemically identical. At the most there could be an insignificant difference in purity. If it is R-134A it is the right stuff.
