Re: Jacuzzi Bus IV
hmmm. there are three possible solutions that pop into my brain.
might need a volt meter to find the problem. first, make sure that 12 volts is going to the heater and that there is a good ground. If those check out, i'd try and spin the fan by hand just to make sure it spins freely. Those are 2 speed fans, and i believe they were only wired to turn on in "high" mode.
if you don't have 12 volts at the heater, then check the switch and see if it has power to both sides. I really don't remember exactly which switch it is, but if you open the electrical panel on the outside of the bus near the drivers seat, you should be able to see the business end of the switches on that panel. Like i said before, i think the switch is labeled as one that controlled the original a/c unit. There should only be 1 or 2 that appear to have "new" wires running to them. One for the back doors, and one for the heater. I don't think it'll be a blown fuse, the bus is equipped with auto resetting circuit breakers if i remember correctly.
