Car Forum / Ford / Ford Explorer / May 2006AC does not work, can't recharge
I have a '94 Explorer and the A/C stopped working. I checked the pressure on the low side service port and there was nothing. I used a recharge kit with uv dye to spot a leak and could not find anything. I used the goggles that make the uv stand out and even used a higher wattage blacklight to spot anything. No apparent leaks. I even looked in the condensor housing and couldn't see anything. Any ideas? >I have a '94 Explorer and the A/C stopped working.

What do you mean "can't recharge"? Were you able to refill the system? Does the compressor clutch engage? More info needed. I was able to refill it, it didn't hold pressure though, sorry, I thought I was clear. As far as "can't recharge", I meant I put in refrigerant and there was still no pressure after it. I don't know about the clutch engaging, I'm just going by a haynes manual, and its short on details. Can you explain? Could that be the reason why I can't find a leak, yet there is no pressure? >>I have a '94 Explorer and the A/C stopped working.

Bad compressor? Isnt that what build pressure?  Signature- Zilla Cary, NC USA (Remove XSPAM) > I was able to refill it, it didn't hold pressure though, sorry, I thought I > was clear.

I thought it might be the compressor, but I thought the pressure would stay the same instead of going all the way down after a recharge, but like I said, I'm working from a haynes manual with very basic ac knowledge. >Bad compressor?

If I remember (vaguely) college thermo-goddamics, compressing freon (increasing pressure) lowers its temp, cooling the pipes it flows through, and then the fans blowing you that cool air. PS, I hated that course! :) Signature- Zilla Cary, NC USA (Remove XSPAM) > I thought it might be the compressor, but I thought the pressure would stay > the same instead of going all the way down after a recharge, but like I said, [quoted text clipped - 7 lines] > >> >What do you mean "can't recharge"?

Compressing freon is an endothermic process (increases heat)... passing the high pressure gas through the condenser (funny name, isn't it?) condenses the high pressure gas into a high pressure liquid. The liquid is delivered to the evaporator through a restriction (most commonly, an orofice tube). As the freon passes through te orofice tube, the pressure drop allows the liquid to "boil" into a gaseous state. This boiling action takes place at something well below freezing and removes latent heat from it's surroundings... For the original poster.. if you don't understand the system, leave it alone and have someone versed in AC repair attend to it.... anything you might try at this point in the game will only increase the eventual repair costs... FerKrissakes.... if you guys don't know how it works... ASK!!!! Pretending that you know what you are doing is like pretending you have a big dick... someone, somewhere, somehow is going to embarass you... > If I remember (vaguely) college thermo-goddamics, > compressing freon (increasing pressure) lowers its [quoted text clipped - 20 lines] > system? >> >> >Does the compressor clutch engage?

Jim, I'm not at all embaresed by my small penis, it gives me plenty o' satisfaction. But I am having AC problems, not penis problems. Also, an endothermic reaction is when there is energy put into a formula to create a new formula. Heat usually is the energy, so there would be a decrease in heat, thus a cold feeling. I don't like taking my vehicle in to the shop because I always have to pay more than I have too. I mean come on, how many hours does it take to put on a serpintine belt again? They were gonna charge me for 4!!! Took me 15 minutes, i was just lazy and didn't want to do it, so I figured I'd have the shop do it. Oh yeah, did I mention another shop wanted to fix the ball joints that didn't need fixing and my tire was gonna come off. That was 5 years ago. Tires still there and there still is nothing wrong with them. So, if I can't get this friggin ac to work, I go without ac, so there won't be any more costly repairs. So, how does one check to see if the compressor clutch engages again? >And, quite obviously, you didn't learn anything from it....

Any ideas? first do your basics if you have a voltage reader test to see if the comressor is recieveing any thing so it can turn on if that has been checked then there is a I think its called a relay switch, Its usually wilbe by the tank that holds the refridgerent and oil it will have 2 wires coming out. |
