A/C button.. on 99 pathfinder SE

[core]

hello again.. i was playing with the A/C button and when pushing it down, the button does not light up..does this mean the A/C is not working or installed ? unfortunately, I cant test it since we are in the middle of the winter here.. any advice is greatly appreciate it .. thanks in advance.. :help

the fan switch has to be on for it to work otherwise it wont light up.. but if your fan switch is on and its not lighting it may be your switch is bad.. to test your a/c by alternative methods set your controls as follows.. fan switch on 1 , mode dial on defrost, temp dial on full cold,with the car running after about 10 mins check the air tamp coming out of the windsheild vents. Does it feel like the a/c is running is it ice cold? also you can set the controls like that and go under the hood and look at the A/C compressor drivers side of engine near the top is the center of it spinning? this would indicate all other functions of your A/C is working so it may be a bad switch.

If you get no cold air and the compressor is not spinning it is likely the system is low or out of freon due to a leak. Or a pressure switch in the system has gone out.

Hey,

I have the same problem on my '99 Pathfinder SE...it just recently started that the AC light won't turn on. However, I think it's just the LED (light) in the button because the AC seems to be running just fine and cold as usual.

And yes, I CAN test it here...because I live in Arizona...where you need AC year round.
