Fan not turning on

[Nilao]

Oh and both I have installed on suspensions to use as dump valves were stuck in the open position. I had to manually cycle it the 1st time with a small flathead screwdriver. Once they were freed up they worked perfect every time. I'm not sure if it is due to them being bounced and tossed by the shipping company but if you put it on and it doesn't cycle try to manually cycle it without the air fittings installed.
