so.. i dont really like asking for help, i prefer searching,

but after searching for quite a long time, i havent found anything definate.

so basically, the heater blower doesnt work. i've checked fuses, relays, and cant seem to locate the problem.

it doesnt work on any of the settings, so suggestions would be appreciated.

things to check and so forth.

thanks in advance.

Does it just not blow at all? Do you hear it turn on?

I had a problem where it wouldn't come out of the vents when recirculation was on.

Unplug the blower motor. Check for power and ground. The motor works on +12V in and a variable ground through the resistor, if you have power than the motor is bad. If you have power but no ground, the resistor is bad.

if it stopped working all of a sudden, id say the motor is bad. if the resistor was bad im fairly certain it would still work on HIGH

alright, motor should have 12v, and variable ground.

power is good=motor bad.
power without ground = resistor. do work.
