Hi Mark

The first thing about this problem is that

1. Check the voltage at the 2 pin coupler with varying the blower
speed. the specs are in the shop manual.

2. Check the resistance the motor side.

3. Removing the motor is not easy in accord if it is not correctly it
may lead to entire HVAC servicing

4. Before doing any work disconnect the battery and remove the ECU.
After you have removed the motor..( in case you deciode to do so) re
connect the ECU .with this procedure the MIL will not come on.

After that you can drive the vehicle.
