99 dodge caravan: heater fan quit working..ac..fan switch, no voltage

This answer was rated:

have a 99 dodge cravan. front ac& heater fan quit working,, rear fan and ac pump run,,,
checked fuse, ok. pulled dash and checked fan switch, no voltage at switch

Hello I will help you with your question,

 

If you have no voltage at the fan switch the blower resistor is the likely culprit. The blower relay is fed from the fuse in the underhood power distribution center, with the key on you should see power at the blower motor and terminal #5 on the fan switch. If there is no power to the fan switch on #5 either the fuse is open, the relay is not closed or the blower motor is open

The blower resistor is located under the wiper module on the engine side of firewall. There is a connector kit if the wiring/connector for the resistor is burnt

The blower motor and its connector is behind the glove box
