HELP Any owners of 02 Winnebago Adventurer W22 Help

I have been trying to fix a dash A/C blower problem ( another post), with no luck. Call Winnebago tech and we started looking at the wiring schematics for my coach. Problem is the fuse boxes on there schematics are NOT what our in my coach. I'm attaching the pictures of my fuse boxes, if some folks would look at them and see if they are the same as your, and if not could you send me a pictures. I trying to see if the blower fan has 2 fuse.
HELP

I have a 2002 Winnebago also on a W22 chassis and I have the same 2 fuse boxes. One is under the hood and 1 is under the dash. I do know that the fuse panel under the dash the relay on the bottom right controls the fan motor also. I turned my fan on and pulled that relay and my fan went off. Hope that helps.

Thanks so much for your reply. Question, was the fan on high when you pulled the relay, did it stop? My problem is my fan runs in the 3 lower speeds, but not high. I tried pulling the relay you ID, the lower speed did stop. Again thanks

find the speed reducer in the fan housing. you have to look for it. its the same blower control on cars. the high speed is burned out. you can get it from autozone. i do not have the number.

I replaced the blower motor resistor (speed reducer), only controls the 3 lower speeds. Also replaced the High blower motor relay, still no high speed. Tring to see if there is a second fuse just for the high side, bur can't find on wiring schematics. Thanks for your reply.

I just checked and the fan goes off when I pull the relay on all speeds. If that relay is out the fan does not work on any speed.

May be it is the control knob itself that is not working.

Below is a cellphone snapshot of a hand-drawn diagram of how the dashboard heater/airconditioning fan control on my old coach works.

Until they went to computerized controls or thermostatic controls the overall concept was the same for decades. The slow speed of the fan had the most resistance and the lowest voltage, medium speed had some resistance resulting lower voltage, high speed had no resistance and full voltage. In every situation where I had to work on a automotive fan the resistors were positioned inside the fan housing in the fan airflow.

In your case I'll bet that the switch is bad, or a connector is open. You'll want to check the connector(s) on the resistor assembly and on the back of the switch.

Since high speed pulls the most current, and automotive style connectors are tend to increase resistance (and therefore generate more heat) as they age, I would not be surprised to find an open connector or a connector with a melted or deformed plastic body on the back of the switch.

Dorman is an automotive vendor that makes replacement connectors.... You an find them at NAPA stores. In my case I bought a replacement connector, it came with pre-crimped short pigtail wires... They obviously expected people to cut off the old connector and use crimped bullet splices to attach the new wiring/connector. I did it my own way... I used a sewing needle to pop the release flag on the side of the pins and slid the wires out of the new body. I then took a few cellphone photos of the old wiring/connector so I could match the colors and the positions, then did the same with the old connector (pop the pin release, slid the wires out). I used small needle-nose pliers to reshape the slightly bent (female) pins to tighten them up, then I slid the old wires into the correct positions on the new (un-deformed) body. The result is that it works fine, looks stock, and with no extra splices.

I don't have your model so I can't compare, but I'm wondering if the relay is actually working when you place the switch on high? It is possible that speeds 1-3 run through the relay when it is Not activated. When activated it then switches power directly to the blower motor. I'd pull the cover off of the old (or new) relay, reinstall it and see if it is actually working. If not, then place the switch on high and manually engage the relay and see if that fixes it. If is does, then you know the relay isn't grounding and the problem is the ground. Have you confirmed that the white/blue is actually grounded?

I now have all 4 blower speeds

I now have all 4 blower speeds. The fuse for the blower motor is NOT any of the 3 marked “Blower or AUX FAN” under the hood. It is under the dash on the left hand side (see attached), lower right corner. Thanks for all the help.
