if i'm on the freeway and i have my a/c on, it's fine, but once i get off and in neutral, it starts making a buzzing sound. well, more like a vibrating sound, what could be the problem? TIA everyone

 

do you feel a difference in the "cooling" power

 

not really, but on really hot days, i get scared, and i turn it off. my temp gauge goes up, but i don't really call that accurate...

 

are you sure the buzzing sounds isnt you ABS?

 

almost positive, it only makes that sound when i have the a/c on, and i'm not moving fast.

 

Open the hood & check around. Maybe it makes the noise even when you're driving faster but other noises cover it up? Couple things I can think of...

AC compressor belt is doing more work when the AC it on. Maybe its loose & humming a bit? Loose bracket holding the compressor? Bad bearing in the idler pulley for the AC belt?

Radiator fans run when you switch the AC on. Maybe one's not balanced real good or its rubbing on its shroud?

 

you have too much freon in your system.. release some of it till it fixes it.. release it from the high side...the outsde heat.. raises the pressure inside the lines and makes the compressor shut down and makes that awful noise.. im pretty sure the sound is.. breh.. kinna sound am i correct...

You should take it somewhere that recovers refrigerant instead of just releasing it.

But you might want to measure pressures to make sure that it really is overfilled.

 

on the driverside theres a little **** near the headlights with a blue cap that ses H on it.. open it and stick a small little screw driver in it.. if you push to hard it will blast a grip of freon out.. just ever so gently do it

since you in san diego i can do it for you .. its no biggy im pretty sure you can do it yourself tho
