Question about 2002 Dodge Grand Caravan

2 Answers

The Heater/AC fan runs all the time on a high speed. Turning the fan speed dial down has no effect, the fan keeps running. Pressing the "power" button off on the heater/AC unit does not turn the fan off either.

    Wipers keep running when dial is off. They do speed up when put on high.

Find the main blower located normally passenger side feet area. on the unit you'll find one or two plugs on a control module. replace that control module which controls the speed and swith off function via the dashboard console.

if you know someone who can solder or do basic electronics get them to replace the Thyristor normally attached two a big heatsink.

good luck

What does it mean when your heater /ac keeps running after the car is shut off


The most likely problem is the blower motor resistor/module is stuck on high speed. The high speed relay is fed power all the time. If it sticks the blower will run even with the key turned off. The typical fix is to replace the module. It can be found under the passenger side of the dash near the blower motor.

Overheats unless ac is running


The thermostat may be stuck. If it dosent open then the engine will overheat. If you turn the ac on then the air rushing around the engine will help cool it down. Replace the thermostat and it should fix it

Heat/ac fan only blows on high


Check the heater control switch,,,,,and the number of wires at the heater motor....Some motors have more than one winding...in which case there will be three or more wires going into motor..there can be burnout in those windings and will require a new motor....check the plug which attaches to the motor....can be bad connection...or at the switch.....but if there is only two wires....then the heater switch uses resistors to slow down the different speeds...and direct connection for high speed....and the problem is definitely the switch...

Subject: 2004 isuzu rodeo...my ac/heater blower is not working


The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

1995 explorer heater/ac blower motor


I would check to see if there is a short on the fan controller switch and the motor. sounds like a crossed wire, especially if it's ignoring your speed selection and running when the key is out. could be near the fuse box under the dash. the cig lighter circuit is live all the time as well as a couple others, it maybe crossing with it. I would pull the fuse panels assem down and check for crosses and shorts.
