A/C gets hot when accelerating.

[The Green GT]

When i am accelerating my A/C seems like it is just on vent. It blows warm air. Once I get back to cruising speed, it works fine. Im thinking it might have something to do with my underdrives not making the alt put out enough power and when im accelerating the motor is draining all the power and has to cut the A/C off.

What do you think?

I think the computer cuts the A/C at WOT. Mine does it. All my EEC Fords have. It's normal. Nice to know you're staying at WOT long enough to notice the A/C cut out.

no, not at WOT. Just normal accelerating.

And mine dosent cut out at WOT. I can go WOT and if I turn it off while going WOT I can feel the power come back when I turn it off.

The WOT info was correct. The WOT relay should kick off the AC compressor at around 3.7 TPS volts (The computer doesnt see WOT as needing the pedal buried).

But given the info on the above-post, do you know if the AC is still cold in the other vents? It seems to me that there's a check valve to hold the HVAC settings when manifold vac goes away (like while getting on it pretty good). WHen this vac is lost, the vents default and you can lose the vents that are at chest height.

Good luck.

thats gonna be a waste of time. thats not the problem. i had a few different ac problems last year and what your describing was one of them. my a/c works now and i still have pulleys. i can see if i can dig up my ac bill but i think the problem was the cycle switch/sensor. kinda by the fire wall on the passenger side. anyone know what im talking about?

It sounds like you're talking about the low pressure switch. It's the system safeguard if refrigerant pressure (ergo volume) falls too low.

Hey didn't you have a post a week or 2 ago about your AC having problems. I may be wrong as there as has been several AC related issues these days. If so what was wrong with the AC and what did you do to correct the issue?
