2002 CHRYSLER T&C FRONT BLOWER NOT WORKING ON ANY SETTING

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.

    Thanks for sharing your experience-I was wondering what voltage you got with the blower turned on? How would you check the brushes?

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.

    Aaaaaaaand it turns out mine must be electronics! I went back out to test it and the all the blower motors are working again! I think I might have a computer problem as my remotes stopped working a few months ago too.

    Best of luck with your problem!

    FYI: A blown electric motor will have infinite resistance as no current will be able to flow. You could hotwire (carefully - there is a lot of power in your battery!) the motor directly up to your battery. If it goes, it is unlikely that the problem is your motor.

I have a 2002 town and country Chrysler I turn on the a/c but in the front it wont blow cold or hot air but in the back were I seat my kids throughs cold air in the back


Your van apparently has dual heat and air and it sounds as if your rear unit is working and your front is not. Will the front blow at any speed? or is it completely dead? If it will only operate on a medium setting you should have your blower resistor changed out, but if it does not operate at all, check for voltage at the blower motor plug in. If you have power but the motor is not running then have the blower motor changed.

No Front Heat 2003 Dodge Caravan - Tried most everything


If I am understanding you correctly, the blower fan is not running. You will need to take things apart until you can get to the blower itself. (Or you could test for voltage at the blower control switch) But I am guessing it is the blower that has gone bad, not the switch. However, they usually get noisy, and then go bad. Test for 12 volts going into the blower motor. If you have voltage at the blower motor, and it doesn't run, replace the blower motor.

Rear blower: only works on high when set on cold, won't work at all when set to heat


I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

Rear A/C does not work. it will not come on, front works fine but rear does not do anything, front driver control turned to rear pass operation NADA,front control turned for driver control NADA, cannot...


since you know where the blower motor relay is for the rear, have someone turn on the switch while you touch the relay. if you feel a click then the relay is good an trying to turn the rear blower on. that would mean you have a bad blower motor or bad blwer motor resistor for the rear unit.

Front blower stays on high, if I pull front blower relay it sounds like another blower starts blowing. If i turn switch to off the same blower starts as it did when i pulled relay


Open and remove the catch that holds the glove box. Behind the glove box you'll see the air duct system. Directly in front of you notice the part with screws holding it in place on the duct and wires plugged in. This is a control for the heating and A/C system. Depending on your type of system controls, (manual, you adjust temperature or automatic, you set digital temperature) you can replace this unit. Unplug the unit, remove screws and remove control unit. Take part to NAPA Auto Parts for a replacement part. They had the manual part about $25.00. Mine has the automatic controls and I had to go to dealer for replacement, mine cost about $65.00. This is easy to do and fixed my "out of control heating and A/C system".
