No heat in our 1997 Dodge Grand Caravan

30

Asked by Susan_Johan Nov 23, 2014 at 02:45 PM about the 1997 Dodge Grand Caravan

Question type: Maintenance & Repair

It has a brand new Radiator, brand new heater-core, brand new water pump, and brand
new tested and working thermostat. Still no heat. The fan works and when selected the
air blows out the defrost, floor, dash etc. We are stumped!
Thanks for your help with what to check/do next!

Check the blend door actuator motor under dash at blower box,it controls,the heat and cool,setting,you may get lucky and just left it unhooked when heater core was installed.

The most common thing I have seen for this is the actual temperature control switch. When you slide to cold fully you get cold air and when you slide it fully to hot you expect to get hot or at least warm air but no. Try, after you fully slide to hot, to slide it back just a little bit and see if the air starts to get warmer. Slide back a little bit and wait 5 or 10 seconds in between adjustments to see. If it does then you need a new temperature control switch. They only take about 30 minutes to change and aren't too expensive.
