1999 Fleetwood Flair Dash Heater - A/C Switch
Ok, I am a newbie to this forum. My 1999 Flair ingested a shop rag into the heat / ac blower squirrel cage, and destroyed the fan motor. that has been replaced, but will still not operate. I am now working with the dash controls. If I apply test power supply with a lead from the cig lighter to the red wire plug on the switch, all is fine until i move the fan speed, and then it blows fuse on my external power. Thus, i assume the control switch is shorting out? Am i correct that red is "power in"? I dont want to buy a new control switch (almost impossible to find) before to confirm this problem. HELP!

Welcome to iRV2. 
Sorry you first post is about problems .
Is your coach a class C or A ?
Fragments of the shop rag could have got onto the speed resistor block causing your short .
If this is on a class A chassis have you seen anything that would indicate the brand of dash HVAC unit ? Evans ?

Right now i am NOT convinced that power is coming into the dash controls. On the fan speed toggle, I can not get 12 vdc to show up on any of the wiring harness pins. i am assuming the red wire is "power in" ??? i need a wiring schematic for the denso control panel. i can get 3 or 4 fan speeds to work when i touch the external power source to the pins on the right side of the wiring harness. Still need HELP! Roger
