my ac in my car seems to "turn on and off" continuiously.. why i say that is the compressor will work, then seem like its turned off, then work and so fourth.. i can feel the power surges when it does that also... what could be the problem??

 

maybe a short or bad ac clutch

 

Low pressure switch or low on freon.

My guess.

i have to agree with the bad clutch on the compressor.

 

any other thoughts? i was hoping it was something small.. actually the compressor is something small, i just dont feel like replacin it had to do my wifes last summer..

btw thanks for the input so far.. give me some other possibilities before i start searching!

could using one of those do it yourself freon cause something to go wrong? ive only had the car for 2 months, filled freon a week after i had it..

 

OK, so you already filled it once?? It wasn't doing this b4 was it??

When an a/c setup gets too low on freon, or the low pressure switch goes bad, the a/c compressor will engage and disengage the way you have described.

Start with those, as they are the most likely, and cheapest repair.

 

well thats the thing.. i turned the ac on for a good 5 mins.. no probs.. its after it warms up and you actually drive for about 5 mins it starts doing it.. where the heck is the low pressure switch at?

and yes i have filled it once..

btw, this is my first car with ac all my other ones, my turbo did not allow it

 

bump for some more thoughts and possible answers :D

 

Maybe I'm misunderstanding but what I read seemed to be describing how the compressor is supposed to run. Any car I've had...specifically in a 4 cylinder where you can feel the power changes....the A/C kicks on to cool some air then will kick off...the A/C continues to blow...then depending on how hot it is it may kick back on in a minute or two or a few minutes like 5. Still have ice cold A/C on my civic and it runs like that.

 

Probably a leak somewhere. Same thing happen to my wife 95 civic lx. Turn out there was a leak on the ac evaporator. Replace it and problem was solve. Ice cold AC for the summer.

 

well i'll go and get some of that green freon and fill it up to check to see if its leaking anywhere.. thanks for the input guys..
