You probably have a faulty blower motor resistor, this electronic part controls blower motor fan speed. This part is located near the blower motor, unhook the electrical connection and you will see 2 screws holding the part in place. This part looks like some type of circuit board, Good luck, Gary
There are two things I can think of that may be causing your problem. First the blower switch in the dash may be bad if you do not have an electronically controlled blower, if you do it could be the control unit itself, but usually they stop working alltogether. The other part which may be bad is the resistor pack on your blower motor.
If your blower has four speeds on it like most blowers these days then this resistor pack will have four resitors mounted on it. They look like coiled wires. These resistors vary the voltage coming from the blower switch so you have different blower speeds. Kinda acts like a filter dropping the voltage for the lowest blower speeds incrementally.
If you want to diagnose this yourself it shouldn't be too hard. You will need a 12 volt test light or a multimeter to test for voltage. The blower motor should be located unther the hood of your vehicle on the passenger side against the firewall. It looks like a round black box with wires going to it. Where the wires connect to it the resistor pack is on the other end of the connector inside the motor housing. There are usually two screws or bolts holding it into the housing. If you take these bolts out it should come right out. You can visually inspect it and you may notice some charring on the circuit board where the resistors are.
I would measure power with you test light from the connector before it goes into the resistor pack. If you are receiving power at all blower settings then your blower switch is likely good since this feeds the signal to the blower motor.
You can then use a multimeter to ohm out the resitors on the resistor pack. If any of them show to be open you have a bad resitor coil there. You have two options at this point, you can unsolder the old resitors that are bad and try and replace them with comparable resitors from radio shack. Or you can go to rockauto.com and order a new resitor pack. They run about $16.00-$20.00.
replace the blower motor resistor. follow the wires from the blower motor to the resistor. the resistor controls the speeds on the blower. this is a very common problem in the winter time do to condensation coroting the circuit board on the resitor
Check all your fuses.( you probably did, but do it again, one at a time) it seems like your control pannel is not getting power. See what wire is the power for the control pannel and bypass it with a jumper wire, giving it power and see if the blower works. Be careful though, make sure you find the correct wire that powers the control, or else you'll burn the control.
your chrysler will need what is called a blower motor resistor this is located on blower motor air box under glove compartment next to your blower motor it will have a plug of wires coming out of it double check your wire at the plug if sighns of wires overheating replace the wiring and plug.
