for the mains switch for the I/C spray, i replaced the 5amp fuse yesterday and all seemed fine, took the car ou tody and still ok but then after a while it went again, i dont know wether it blows when the its about to spray as its automactically sprayed, the feed comes off the cigarette lighter and i cant see any loose wires, so now im a bit
I might just re-wire the feed from the cigarette light to the switch and go from there.

 

thanks for the replys

found out it was the pump, so have ordered a new one
