2002 Grand Caravan. The rear heater also has a resistor for the fan speed control.(3 speed) It is located under the rear passenger side plastic cover. You can take off the rear tail gate lower plastic piece and this will let you pull out the side panel. You can reach in and take out the two screws that hold in the resistor and unhook the wiring adapter. You do not have to take off the whole side panel as you can reach in from the back. The resistor unit can be bought at you local dodge dealer.

There is a resistor bank for the front fan mounted in the heater fan housing behind the glove box door.  I bought a new one from the local Dodge dealer and changed it out.  I don't know if this is your problem, but I had the same symptoms.

Engine tepmrature goes up or down when i turn on the heater


That is pretty much normal, the heater blower fan acts like the radiator does and helps cool the water passing through it by extracting the heat from it. then once the car inside temp warms up it goes back to normal. Nothing to worry about.

My mazda protege is having a heating problem. The temp guage will go up to the normal place as the engine warms up but then when I drive down the road the temp guage goes down to below cold and then my car...


I believe the mazda protege has a separate thermoswitch to activate the radiator's fan. Perhaps the fan keeps blowing until the temperature is too low. Try replacing the fan thermoswitch. Just take care to put in tis place a thermoswitch of the same temperature range.

The heater does not work there is no thermostat in right now and I also have a temperature gage that flux and what she wakes up and down it's normal when moving and go as high or when idling


The thermostat is used for the heating system. It slows the antifreeze down in your radiator to allow it to warm up before its cycled through your heater core. Put the thermostat back in, heater will work. Will also regulate flux temps.

Heater blowing good heat temp gauge not moving and cooling fans not coming on. Unplug engine temp sensor and fans start put plug back on fans stop. gauge never moves


bad gauge or bad thermostat.

Fans come on because when you disconnect, it goes to default mode of fans on high speed.

Why is my heat/front defrost not working very well. Only shoots warm air? And not very forceful.


hi from uk can i offer this advice ? when you start engine let it warm up a little then drive untill temp guage reads warm at least ? then when you put front screen defrost on only select screen and No 2 speed then as temp reaches normal screen will clear fully if you select full speed on heat blower to clear screen at first start it will not work because the coolant from engine passing thro the heater matrix/radiator will be rapidly cooled by fan of heater TRY IT? in years gone by it was common remedy if you were stuck in traffic and temp rose towards hot you could cool system down by putting heater on full heat and the fan on max this cooled the engines coolant as it passed thro the heater ?hope you understand how heater/fan should work for optimum efficiency my wife has owned 2 of these accents and never had heat/demist problems it is surprising how many people consider the demist/heater systems are poor on many cars not just hyundai hope this helps best wishes

Can not find heater control valve 2000 expedition


what year? for 2000, there are no control valves. It mixes a/c air with heater core air to blend the right temp.

SECTION 412-02: Heating and Ventilation 2000 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Heating/Defrosting The heating and defrosting system has the following features:
  • Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside the vehicle.
  • Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
  • Controls the A/C blower motor speed.
  • Cooling or heating can be adjusted to maintain the desired temperature.
  • Uses a reheat method to provide conditioned air to the passenger compartment.
  • The blower motor draws outside air through the A/C recirculating air duct, except for MAX A/C cooling, when recirculated air is used.
  • All airflow from the blower motor passes through the A/C evaporator core.
  • The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
  • The temperature blending is controlled by the temperature blend door, which regulates the amount of air that flows through and around the heater core, where it is then mixed and distributed.

Fan on High Only


The fan motors use a set of resistors to control fan speed. The lower speeds generate more heat in the resistors and these tend to burn out. While it is possible the switch could be the issue, I would start with the resistors. It is usually a module located somewhere near the blower motor.

Note: One of the reasons these go out, is that with time the bearings on the blower motor go bad and the motor takes more power to run. If the replaced resistors fixes the problem, but then fail too soon, look at replacing the blower motor as well.

2001 tahoe front heater not working, rear heater blows warm air


Notorious for plugged heater cores. Also updated plastic restriction couplers mounted at heater core available from dealer. Try back flushing heater core. Run engine till its at operating temperature then carefully hold the inlet and outlet hose breifly with heater fan on high if hoses are nearly the same temp then flow is good , if not then core is plugged.

2001 tahoe front heater not working, rear heater blows warm air


I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?
