Help!!! I cant find them and its HOT!!!

[Tommy]

My a/c isnt good I need to repair it but cant figure it out and with the temps in the 100's for the past 15 days and for the next week at least I need to repair it before my 2 year old son sweats a lake in my car. Ok first off my a/c fan wont come on its the relay but Idk where it is can someone point me in a place to look? Second Ford did a horrible job converting it to 134a a long time ago so it leaks out over the winter and they didnt put the right fittings on the lines so it makes it difficult to hook to. Third with the a/c on it works going down the highway but only cools to 60 degrees and thats at 70mph. Please help if not for me for my son

You say you have an AC Fan which leads me to believe you have an Automatic transmission (only autos came with a separate condenser fan).

This info might help others, help you locate the relay.

ok relays are in the driver fender behind the headlamp. you can get the retrofit fittings from any McAuto parts store. as for the cooling capacity, you should be seeing about a 40* differance between the vent temp and outside temp. so at 100* ambiant, 60* vent temp is good.

[Tommy]

Yes it is an automatic I didnt think to say that. I will look behind the headlamp. So my a/c isnt doing to bad if there is a 40 degree difference it was 102 degrees on my way home today and it was 60 degrees in the car, now I need to figure out to make it better Thank you guys.

We wrapped Skims AC line with Foam wrap and then zip tied it, im thinking we should put some sort of aluminum around it too so that the foam doesnt get heat soaked

[Tommy]

What did wrapping the lines do? Did it help much?

That's what she said....

Which line did you wrap? The Big or small one? If I put a condenser fan in ( I have a 5spd), how do you hook it up ? Make it run all the time, or only when a/c is on? How do you hook the wires? Lots of damn questions I know.:tongue9:

[navdoc101]

Skim & Euro , can you answer my questions? Both of ya'll have done this, right?
Sorry for the hi-Jack, but I think Tommy will need the answers also

[john1290]

when in doubt it never hurts to insulate both of them so that the ac can operate more effeciently in general

[navdoc101]

Thanks John!

The large line is the low pressure side, i.e. the cold side. The small one is the high pressure side, i.e. the hot side.

you wrap the large line. putting a fan in should be done by using a relay that's "T-ed" into the clutch power wire so it runs with the A/C (small current side sees the clutch power wire, the big current side should be a ground switch for the fan).

you're looking for something like THIS where 86 goes to the clutch power wire, 85 is ground, 30 comes from the fan (ground wire), 87a stays disconnected, and 87 goes to ground.

Thanks, Festy & Larry. I was thinkin' , maybe I could splice into the other fans wireing . Would that work okay?

[FestYboy]

no, don't want to do that as the fan circuit is built for 1 fan. if you add an aux fan you need to have it on a seperate fused circuit so that you don't overload the wiring.
