Ok the motor is not a problem. Locate any and all fuse banks, then any and all fuses related to the low and med. setings. Replace any blowen fuses(burnt center with the metal strip broken)with like fuse(20 with 20 only)if you replace with a higher or lower fuse(20 with 30 or 10)you will damage your electric system. I have had your isue in a 99 Durango. i hope this helps.
