I've got a 96 Caravan. The blower motor for the heater/air conditioning works fine, but recently, the switch seems to have gone wonky. The blower motor will only come on if you turn the switch all the way up to the max. The lower speeds don't work at all.
Could this be just the switch?
Are there any relays or fuses I should check first?
Thanks.
The heater resistor block is bad, the default is hi blower all the time, its easy to replace, 2 8mm screws under the glove box,
Are you sure about under the glove box. My 96 Caravan has the resistor accessed/mounted under the hood, passenger side firewall, just inboard of the shock tower top. A little hard to see and get to, but not impossible. It was a simple change, and definitely the problem for a high only blower motor.
From your description, the resistor that drops the voltage for the lower speeds is burned out. I don't know where it is located on that model. Sometimes the resistor is located behind the switch. On other models, it mounts in the on the heater core/evaporator enclosure. The resistor usually looks like a coiled spring.
