How can I inspect or repair the Dodge Caravan heater "mode door"? How much must be removed beyond the glove box?
The mode door directs air to defrost or the heater vents, and it is controlled by an electronic switch on the dash. In my case it works inconsistently, making a clicking noise and ending up in the wrong position as often as not. This makes driving the vehicle in certain weather hazardous, as the windshield fogs up uncontrollably.
I'm aware of "Heater Treater", a third party maker of replacement parts for blend doors, but they don't do mode doors as of this writing.
(The same fix should also apply to Plymouth Voyager, Chrysler Voyager, Chrysler Town & Country, Chrysler Grand Voyager, Lancia Voyager, and Volkswagen Routan)
