It's funny how many AC questions come up when the weather
gets hot. If your refridgerant level is low then you have a leak.
It will need to be taken to a shop and have them recharge it
with dye to find the leaks. The compressor needs checked to to
see if it's just not coming on. I am unfamiliar with when imports
started useing r-134a. Some older cars use r-12 which you
cannot buy unless lisenced to do so. If it uses r-134a then you
can try to recharge it yourself by buying it from the parts store.
