The blower fan runs @ max speed in all controll positions including off and even with the plug to the motor resistor unplugged! the only way to shut it off (beside turning the ignition to off) is to unplug two 15Amp fuses. Anyone had this?

 

Switch and/or wiring shorted?

 

Update:
O.K. switch it’s got to be then. Went and ordered a switch from a local dealer, $90 with taxes, ouch! After ripping the dashboard apart, I tested the removed switch and could not find anything wrong with it!? I plugged it in separately and the damn thing works. Then I checked if it works with the rest of wires plugged in, it did! It fixed itself? WTF, will see for how long.
