Here's how I changed out the fan and resistor on my 2015 Itasca Solei (identical to a Winnebago Forza)
Tools needed
Philips screwdriver (one short and one long)
Snake light/camera that works with iPad (wireless wifi endoscope) $40 from Amazon
Drill and bits
Small set of hook picks from Home Depot for $6
1 remove cup holder trim rings (they pull off), then the cup holder screws and lift them out
2 remove two screws, near the floor, holding the cup holder trim molding to its metal framework. The molding will lift off. This exposes the framework.
3 on the right of this framework is a plastic vertical dash trim piece (completes the curve and look of the dash). It should pull straight out
4 remove the cup holder metal framework by removing the four screws and set aside. You will see how removal of the fan is blocked by a horizontal piece of sheet metal bracing (refer to number 1 in my picture). Drill out its five retaining rivets and lift out.
5 replace the fan if required. Unplug the electrical connector and remove five screws and it comes out.
Resistor swap out.
6 lower the first front vertical ac hose by removing two retaining screws at the top of the hose.
7 using your snake light/ camera poked around the corner (refer to number 2 in my picture) you will see the resistor. It is joined by an electrical connector having four wires (red, blue, purple and yellow).
8 I have medium sized hands and I was able with difficulty by laying on my stomach, to get my hands in from the left lower side. With a short Philips screwdriver I was able to remove the screws and pull the resistor down and slightly out where I could work on it. Note I've got a lot of scratches on my hands and arms. Persevere it's doable.
9 in my case, the electrical connector containing the resistor wiring harness would not release from the resistor no matter how much pulling and rocking I did. I used my tool hooks to come in from the bottom to break them loose.
Do the reverse to put everything back together. I didn't use rivets but rather screws and lock nuts in the event I have to redo this at some juncture.
I called Winnebago's help support several times and they gave me advice, non of which worked, so I did what made sense. In their defense they assemble these things and don't get much of a chance to fix them like I just did.
I hope this helps someone else along the way.
Best of luck
Bob
