ok, i had a huge leak and my radiator went out about 3 months ago, now when i turn my ac on and the car is sitting still (like at a red light or somethin) the air from the ac get real warm and has a strange odor then the ac starts to make a hissing noise and the car starts to overheat really quickly. it kinda sound like the ac is turnig on and off. what do you think the problem is??
^^^oh yea i got the radiator replaced and got the leak fixed.
the strange odor might be Coolant.
and the reason why it overheats is because maybe there is some kind of cooling system pressure lost making the system not circulate.
Check for leaks, specially around the AC
