Hey Misn1. If you don't have the schematics for the Fleetwood check the responses from Usual suspects embedded in this thread to help you out for openers. The unfortunate part is that there are more than a few items that could be causing your problem, again UsualSuspect did a great job of providing items to check. First are your fuses ok? If not keep reading. Second ?.. Does your fan work on ANY speed? If so then your fuses are ok and you can skip down below. There are two fuses. 1 is located in the "white" fuse box under the dash. If that one checks out then you might have to check the in-line fuse (picture in thread). More than likely you are going to need to remove both fuse banks in order to get to the harness. It's located behind the fuse banks and you may have to move the air hoses in order to see it. FAN motor works on certain speeds. If it's ok then you are probably going to have to remove the lower portion of the dash in order to get to the main relay and the fan speed resistor module. Take your time with this as you might bust the substraight. start with the screws that will be inside of the main opening by the fuse blocks. There will be some inside the actual vent by the steps as well as the bank with the switches for the lights by the step as well. So if you have gotten this far then you will need to trace some wires out as there are more than a few relays 1.5"x1.5" black boxes. There are a few on the fuse banks and the "main" one is located on the actual fan blower wall itself closest to the steps. To test them out there are some great YT videos out there but you'll need a 12v power supply and multiple leads. I'd just suggest to go down to your local auto part store and get the five pin relay for about $10 and simply change it out and go from there. Have to get on a plane so good luck.
