I have a 1998 Isuzu rodeo 3.2L and I had my truck parked for a couple months and when I finally get it back on the road my A/c has no power. The blue light doesn’t Light up or anything completely no power to the dash that controls the A/c can someone help me figure this problem out I would greatly appreciate it.

 

If the refrigerant leaked out and system pressure is low, a low pressure sensor will not let system kick on. Could also be a fuse, check those.
