my 2000 jeep grand cherokee heater fan works intermitently, just replaced heater core myself, has new fan motor and new kit for dampers, checked connections on fan motor. looking for something else. any ideas?
 

If the blower motor intermittently works at any speed setting, remove the upper and lower steering column covers behind the steering wheel. Check the wirings and connectors including the ignition switch connector for hot spots. Usually if this is the culprit, you can duplicate the issue by slowly moving the ignition wiring from the switch with the key on the run position.
