Fan not kicking in

[rtjohnson1982]

Clutch fan is brand new, we installed it 2 months ago. It’s air driven. Also truck has a PADS A/C system and it’s blinking green saying ac system is working properly. I was thinking maybe the thermostat was going bad but I’ve never had to change one so I don’t know how to tell if it’s bad. Rawze I’ll unplug the ac pressure switch and get back to you. Problem just started so I haven’t done anything yet because I’m unsure of where to start.
