hi, my name is ***** ***** I will try to help you .
here is a diagram for the heater blower circuit .let me know if this differs with the colors of your wiring ,as sometimes the wiring can be for a 2000 or 2002 as well -chrysler likes to change wiring colors between the different years ..
the first thing to look at is make sure all the fuses in these diagrams are good
then go to the source which is the blower motor
disconnect the connector at the blower motor
and turn the key on ,turn the fan on to any speed
check for ground and bat voltage on those two wires
if you have ground and hot then the blower motor is most likely bad
if you have hot but no ground then check the blower motor resister ,this is the ground path for the blower motor .
there may be an issue with the relay as well but lets see if you have both ground and hot to the blower motor first ....jazzmaster ..
