A/C stopped working - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a 92 coupe. AC has worked for the last two years but just recently it completely stopped. I think the compressor and everything is still good because it worked about a month ago.

When I push the A/C button, the little light doesn't turn on. And when I turn the defrosters on, it doesn't kick in either. Any ideas?

fuse under the dash is good.

check to see if you are getting power in and out of the control unit

Check how much pressure/freon you have in the system. The AC compressor is designed to have a safety/pressure switch that prevents it from turning on if you dont have enough freon. You might have a leak somewhere and you dont have enough pressure in the system.

When was the last time the AC got serviced? if never go service it, it doesnt cost much to do it.

If the light isn't coming on - I bet its an electrical issue. Usually the a/c light comes on even if the compressor doesn't kick on afaik.
