Check fuses and relays. On relay just switch with one you no works.

Check the Blower Motor Resistor. This controls the Blower Motor/Fan Speed.

SOURCE: Can't manage to get darn blower motor
you have the dash out? the dash and hvac box have to come out to get enough clearance to get the blower motor out. one of Chrysler's smarter ideas,don't you think?
SOURCE: Hi, my 1998 dodge durango
If you can hit on the blower motor housing and the motor starts, your brushes on the motor are bad and the blower motor needs to be replaced. Used tested unit $30.00 at a junkyard. New rebuild $54.00.
Many posts have stated that the dash must be removed to replace the blower motor. It can be done without removing the dash. I know as I replaced the blower motor on my kids 99 Durango last night but it took about 4 hours. Now that I know how to do it, it would estimate 2 hours.
Remove glove box by opening glove box all the way. Press inward on the both sides of the glove box to allow the rubber stops to clear the catches and lower the box The two outer hinges (plastic) will come off by slightly twisting the glove box upward leaving only the center hinge (plastic) in place. Reach in and push down on the hinge to pull out glove box. Set aside.
Remove side trim panel by pulling back carpet and remove one Phillips screw. Remove panel by pulling back on upper portion to remove clip from frame, then slide forward to remove from lower plastic trim.
Use 1/4" nut driver or socket to remove two screws holding vacuum canister on lower right side of blower shroud. Remove two vacuum hoses noting which hose goes to which side of the vacuum canister (both were green in color on my Durango). Disconnect connecting rod from vacuum canister to vent control by removing lock washer (you may be able to get away with not removing the rod, but the plastic "fin" may break if you stress it while removing the blower shroud.
Use 5/16 nut drivers/sockets with extensions to remove the blower shroud hex bolts. The hex bolts are located in several areas around the shroud (use your finger to follow shroud edges to locate all 8). Some of the hex bolts are very tricky and may require odd positioning of your body to locate and remove them.. I also put several extensions to use in order to reach the various hex bolts. Once the hex bolts are removed, pull the plastic blower shroud down exposing the blower motor squirrel cage.
Remove two of three hex nuts holding blower motor in place. Loosen the third one and the blower motor should come free. I was not able to remove the squirrel cage from the old motor so I broke the squirrel cage allowing me to expose the wire harness and grommet that went through the back of the shroud.
Feeding the wire harness back through the assembled wall appeared to be a real challenge, so I cut the green and black wires at the motor for splicing into the new motor later. Remove the motor and broken squirrel cage and throw the dam thing away.
Remove squirrel cage from new motor by removing retention clip with a pliers. Pull off the squirrel cage carefully by applying WD40 (or other lubricant) to the shaft. You may have to place two large screw drivers or other pry bars underneath the squirrel cage equally across the underside of the squirrel cage slowly prying up the cage. I accomplished this with a helper to hold the motor in place to allow equal pressure from both pry bars.
Cut green and black wires on new motor leaving enough wire to work in the tight area of the motor housing. Strip wires from old harness and new motor and apply **** splices for green to green and black to black. Add electrical tape for extra mechanical strength and insulation.
Place new motor into housing and secure the three mounting hex nuts. Turn on key and run blower to make sure it works. Install squirrel cage and retaining clip on motor shaft. Run again to make sure it works.
Install the balance of the items in the reverse order you removed them.
Good luck!
Now on to replace the rear wiper motor on the same Durango. Junkyard parts $54.00. Time: Unknown?
Replace the resistor. I know you say you tested it.
