finally fixed it

For the last 4 years when driving my class a down the road my rood airs would go on and off.I replaced my confort air thermostat same problem.Finally this memorial day weekend while parked the roof airs stoped and the thermostat was blank.checked for 12 volts at thermostat nothing. went to the fuse box and wiggled the 5 amp fuse and the ac would go on and off.fuse is made on a circuit board.Installed a inline fuse no more problems.
