Combines Blower fan on F3

Mark, Do you have power coming to blower switchIJ If so, you may have a resistor going bad that controls the three speeds of motor. I believe this is mounted on inside of overhead console with access by dropping access door down. Should be a three pin plug-in connector on resistor. Check for power to resistor on three speeds and you can bypass resistor to make sure blower runs. (Part n for resistor is 70257340) Hyper Harvest II

I saw the resistor mounted up there in the console overhead. I will get the test light out this week and check for power. the red wire running from the fuse box thru the cab light and on to the switch
