    A/C blows ice cold when you bypass the cooling fan relay. Anyone know where I can find one? They are specific to the 1.8.

    Places I've tried:
    Ford dealership- only 4 left in existence and Ford wants $80
    Pick-N-Pull- This is where I discovered this relay is unique to the EGT
    Every junkyard in the area- Nobody has the EGT
    Any auto parts store- Nobody carries the correct one. Only the 5 pin
    Ebay- Nope
    This Forum- People arent too responsive...

    Help? Its stupid hot here and I need some A/C. Thanks

    Yes, they only have the 5 pin relay. It looks exactly like the correct relay but with 5 pins and the internals are different

    Post a picture and the location on the car, I can probably grab one for you this weekend at the junkyard. $10 for my time plus shipping.

    The relay is located on the upper corner or the passenger's side of the firewall. On the 1.8's it is the only relay in its location. On the 1.9's there are two there. The markings on the relay are distinct and it has 6 pins. The pictures illustrate that. And sorry I dont know why the pics arent coming up or how to fix it. Just copy and paste the link

    I'm heading out to a yard or two this weekend as well. I'll add it to my list of "to get" just in case one isn't found.

    Thanks for you help. Keep an eye out for a dome light w/sunroof as well.

    yep, got a six pin relay from the location you told me, looks like the picture too.

    Also, this board doesnt support the img code. You have to insert the html link for them to display.

    $10 +4.50 for shipping and its yours! My paypal address is masterian1 at hotmail dot com

    Is this a common problem with EGT's?

    It does if you use the correct format,

    in those tags like that and with out the "" and inserting inline html code does not work as that is disabled on the board.

    Out of curiosity, I have a 91 GT too. My compressor is only about 4 years old, and it now blows hot air. I tried adding some freon, but the compressor just kind of buzzes and wrrrs when I try to add, also my pressure gauge on the freon can seems to say full, but it kind of bounces around in correspondence to the buzzing and wrrring...

    Could this be that 6 pin relay problem?

    I don't really know all that much about A/C Sytems other than the fact that I know how to add and release the freon, I was considering having my A/C system checked at a local A/C specialist but saw these threads. Any ideas?

    Either your compressor is low on oil from your leak or your compressor is bad. Both will cause high pressure on the low side- assuming you were adding freon on the low side as you should.

    Yes, definitely adding Freon on the 'Low' Valve as required.
    To check the Oil level would require removing the compressor, right?

    If it were me, I would remove it. Just because of how easy it is. While it is off you can both check fluid and inspect the condition of the compressor. Make sure there is no metal or dirt or anything in the oil when you drain it into a measuring something-or-other.

    Or. You could just put an oz or two of oil and see if it changes any of your symptoms.


    Here are some other symptoms of high pressure on the low side. Just a little fyi before you start pulling things apart;

    -Orifice tube clogged (just replaced mine on my wagon)
    Will also have frost/abnormal amount of dew on low pressure hard lines.
    -Air in system/poor vacuum prior
    Will cause the low pressure tubing to be hot
    -System overcharged
    -Condensor cooling insufficient/fan faulty


    Happy hunting. A/c work is frustrating for me, personally. I try to avoid it at the shop... but it always seems to find me.. lol :/

    FYI for those monitoring this thread, the relay was not the problem. The A/C works fine when the electrical system is bypassed. The AC switch turns the cooling fan on but will not engage the AC clutch. Thoughts, suggestions?

    Yeah, didn't think my problem would be a relay. Because I'm getting warm air, its just not cold.

    I just have to find out why I can't seem to get any cold air :(

    EDIT : You mentioned Condenser Fan Faulty. That would be the same fan that is mounted on the Radiator, right?
    I'm using a temporary Universal Single speed fan cause my old one burned out and I ordered the wrong fan [the universal one] by accident. Gonna order the OEM replacement next week.

    The currently installed Universal fan doesn't do nearly enough cooling for my car in the Florida heat...would this have something to do with the reason my A/C not working? I know that the Radiator sits behind the condenser...

    And means how I'm on the topic, is our radiator fan a puller or a blower? Does it pull air toward the engine or push it away through the grill? I can't find this anywhere and right now I have it blowing toward the engine, seemed logical enough to me.
