A/C is broken
Ive searched the forums the best I can but I cant decide which way to word the search... ac..a/c...air conditioner...air conditioning... either way the thing that is sposed to keep me cool is not working, and so I'm going to post my question.
I had a 3 hour drive yesterday and I think something may have gone wrong on the way home, I try and turn on the air conditioning today and nothing. The light lights up and the fuse isnt broken and the compressor is turning. I've deducted that I must have a leak. I havent charged the system since I had it replaced 2 years ago. My question is can the freon run almost instantly without a leak in the system or would it slowly be less and less cool? Also, if there are any other things I could do a visual inspection of please help. Thanks again, hopefully this is an easier fix. |
if it had a leak, then it can all leak out overnight (well, enough to cause it not to turn).
At the same time, if the pressure of the freon isn't to the right amount, then the AC relay shouldn't activate the compressor. |
do you hear a "tic" when the compressor comes on?? or does the compresser even come on?
|
no tic that i remember, The truck doesnt even go to a higher RPM when i turn it on. Is it the compressor then?

AC stuff is not a DIY job, take it to a shop and have them pull a vacuum on the system and see if it holds. If yes, refill with R-134. If not, start looking for the leak.

okay, i need help on my ac
it gets really hot out here in california, and i love my 4runner ac it works GREAT. but, one night im driving home and its hot, and i try the air, nothing. it blows air, but hot air, and the heater of course still works. what can i do? i dont hear a click? are compressors expensive? |
wow, no one can help me?
|
I have heard about quite a few people using ES12 over R134a.... I fixed and recharged a friends 86 BMW with the stuff and it is pretty impressive, mainly b/c the compressor didn't seem to have so much drag on the system... especially when the crank fan is spinning with the 100 deg weather we have.
|
mine is in trouble too, i have had no A/C for about 7-9 months now, but here in Belize it is not easy to find someone qualified. if you find out the problem, let me know so i can try it on mine

Check your belts. If there's no drag on the engine that may be your first clue. If all check out then start investigating the piping. Look for Signs of leaks. Ex oil residue. If nothing still take it in and have a system check then a pressure check.
