how do i tell if it is a blower motor bad or resistor bad on 202 ford explorer xlt
when we bought the 2002 ford explorer xlt the blower only worked on high,
last night the blower stopped working at all, not air moving out of vents, can
feel cold or heat if you put hand up to vent but no air moving
Check your fuses and relays first to see if they are blown if they are good use rest light to see if you are getting any power going to the blower motor from the switch but try tapping on it or wiggling the connection clip also because it might have came loose or your switch might have gone out
Disconnect the resistor. Bypass it with 12 volts to the blower. If it works, it should blow on high. If it does not work, then the motor is bad. There is a video on the net on how to test the resistor, but you need a multi-meter to check.
