I don't know what happened, I was with the wife, jumped in and started it up. I hit the ac button.. No light...
I checked the fuses and all are good. I haven't changed anything lately but I do have a slight engine oil leak (compressor has a little oil on it). is there a fusable link somewhere?
I also was thinking.. there is no fail safe for low fuel is there? (I am presently under 1/8th of a tank, I will refill next time I drive)
Need some options..
Thnaks all!

Do a search in this forum for air conditioner, AC or A/C and see what you come up with. If no luck, I would start by checking that the idler pulley is good and your compressor is turning with the engine. Then, make sure your idle is not too low (there is a cutoff for the compressor that will not engage if the engine is below @ 850 rpm).


Which year/engine is this for?

 

Yes, Did a search and couldn't find anything simalar. it is almost like the switch doesn't work. There is no Idle up, and it doesn't matter if I am driving or stoped. no action.

 

yes there should be a low pressure cut off switch that would prevent the compressor from kicking on should the system be low. (there is also a high pressure cut off)

you can put a guage on the system and then jumper the pressure switch to force the compressor on and see what your pressure is.

with out the compressor turning the 2 sides of the system will equalize so you really cant take the pressure with out the compressor turning.

 

Fixed!! After almost 20 years 1987 model.. the switch in the dash came unpluged
Thanks all!
