ha ha tryed the thermo trick no cigar the os fan blows fuses every time the switch is turned on and the ns one works but only on high speed found out if u earth one of the ns orange wires it will still allow the ecu to turn it on but instead of slow speed u get high speed so yeah that works for me so il leav it at that might run a seperate switch in the car so i can go from slow speed to high speed ..as the problem to begin with was the high speed wasnt coming on at all ,,after reading the wiring diagrams i must have a bad relay or somthing ..any way thanks for all the info on this topic
