Heat quit working on levels 1-2-3, then the heat kicked in and out for a few days, finally stopped entirely. changed motor blower resistor. heat worked again after giving a little bang on the side of the heat panel. worked on all levels 1-2-3-4. then heat quit entirely again. worked again. damn well quit again. electrical problem???? i need heat! what do i do!
SOURCE: heat
recently had same problem replaced motor had same problem removed new motor took it apart and found a fuse of sum sort inside which wasent conducting power i cut it out and merged the 2 wire now works fine

sounds like a head gasket problem. A minor leak there will pump compression into coolant and force it out of heater core. Any unusual steaming from tail pipe? Also: if radiator was flushed "in car" sometimes debris does not come out. Try flushing with it out of the vehicle. Jeep radiators are notoriously small for their application if not at at least 90% they will not work correctly.I'd look at the hg first though otherwise, your symptoms seem to be contradictory.

You have to take the glove box off and it is right behind it, need a #20 Torx to take it replace it. The glove box is the hardest part of the job, I just replaced mine on an 05 Grand Cherokee but it didn't fix it for me, was well worth the $8.60 to try though.

You can test both of them once you have it apart. I have given you instruction below. Please follow them as injury could result.
REMOVAL
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
CAUTION: Stay clear of the blower motor and resistor block (Hot). Do not operate the blower motor with the resistor block removed.
Disconnect and isolate the battery negative cable.
Remove the glove box from the instrument panel (Refer to 23 - BODY/INSTRUMENT PANEL/GLOVE BOX - REMOVAL).
Pull out the lock on the blower motor resistor wire harness connector to unlock the connector latch (Blower Motor Resistor Block- Typical).
Depress the latch on the blower motor resistor wire harness connector and disconnect the connector from the resistor.
Remove the two screws that secure the blower motor resistor block to the HVAC housing.
Remove the resistor block from the HVAC housing.

blower resistor is right next to motor under passenger side of dash.
