After going on my first trip with my 97 Excella I'm discovering a few bugs that need to be fixed. #1 is the front light/vent that has an electric fan attached. When I first used this fixture I opened the vent, the fan went on and would not shut off. I did as instructed in the owners manual and backed off the control handle, but that did not shut off the fan. After playing with it for about an hour I cut the 12 volt
power and the fan went off. I was hoping that this would reset the fan and everything would be normal again, but that was not the case because as soon as I put 12 volt
power into the trailer the fan went on and would not go off. I finally had to take off the shroud and and screen in order to get to where the wires were going to the fan and cut one of the wires in order to get the darn thing to stop.
I'm not sure what has gone wrong, but I suspect a bad relay of some sort. Is this a common problem with this kind of fan, and if so can I buy a simple electrical part without replacing the whole assembly?
