Question about 2002 Chrysler Town & Country
3.8 L V6 DUAL HEAT/COOLING SYSTEM. REAR BLOWER WORKS ON REAR CONTROLS..WITH FRONT CONTROL TURN OFF. FRONT BLOWER DOESN'T WORK AT ANY SETTING....
MY QUESTION..HOW TO TROUBLESHOOT THE RESISTOR BLOCK OR THE MOTOR. WHAT OHM READINGS SHOULD I SEE ON A BAD MOTOR? A NEW RESISTOR BLOCK AT DEALERSHIP RUNS $80 DOLLARS. WOULD LIKE TO NARROW IT DOWN AND RULE OUT THE BLOWER MOTOR.
I had the same thing happen today except rear control works period (no conditions). I am going to test the leads to the front blower first while on. If voltage is there, then I will check the motor brushes - could be a cheap easy fix (~$6 + time). Alternatively you could replace the motor ($50+ plus time). If no voltage there then it is probably electronics.
It could be a resistor(s) but I believe it is unlikely that *all* the resistors would go at the same time.
