Have a 2004 Chrysler Town and Country with a heating issue. We've checked all the usual suspects and were told it could be electrical. Any ideas on how much we might have to spend on repairs?

have the same problem?

What's it doing? Starting with the '96 redesigned model, the heater is controlled by a very unreliable, complicated, and unnecessary computer. This is because people demand such toys as dual zone heating and the ability to blow varying percentages of air from multiple places at once. That means a computer is involved and reliability goes away and repair cost is often as high as a monthly car payment or two. Just be happy you don't have a GM product. That's how they make their money.

First you must tell us what the symptoms are. Cold air? Fan doesn't blow air? Air comes from the wrong places?

The car isn't blowing any air at all! But, the vents do get warm as the car is driven. The car isn't dual climate zones, just basic.

First check the fuses under the hood and in the van. Next, measure the voltages on the two wires going to the fan motor. If neither has 12 volts, swap the fan relay with one of the other relays like it. The thermal fuse could be burned open too. It's part of the resistor assembly for the different speeds. The thermal fuse usually pops when the motor is drawing excessive current and must be replaced. If both wires have 12 volts, suspect the fan control module. If you find 12 volts on only one fan wire, the motor is defective if it isn't running.
