I have a 2004 Pacifica. The heater is not blowing to the front (feet, face or defrost). Air is blowing to the rear feet only, but it is not warm. I tried to recalibrate the heater by pressing the power and recirculate button, but it did not solve the problem. I disconnected the battery, but that didn't work either. Last week my battery had trouble holding a charge, but it was cold and now seems to be fine. Not sure if that has anything to do with my current problem. I am a mother of 2 small kids and need a heater. It is cold and snowy here right now. HELP!
Do you

Hello . thanks for the donation .. much appreciated

Start by checking the fuses and then doing the following checks !

DIAGNOSIS AND TESTING - BLOWER MOTOR
BLOWER MOTOR INOPERATIVE
WARNING:ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEELS 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.

Check the fuse (Fuse 10 - 40 ampere) in the Intelligent Power Module (IPM). If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.
Turn the ignition switch to the On position. Be certain that the heater-A/C control power is turned on. Check for battery voltage at the fuse (Fuse 10 - 40 ampere) in the IPM. If OK, go to Step 3. If not OK, proceed to diagnosis of the front blower motor relay. (Refer to DIAGNOSIS AND TESTING - BLOWER MOTOR RELAY ).
Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the front blower power module from the module connector receptacle. Reconnect the battery negative cable. Turn the ignition switch to the On position. Be certain that the heater-A/C control power is turned on. Check for battery voltage at the fused front blower motor relay output circuit cavity of the front HVAC wire harness connector for the front blower power module. If OK, go to Step 4. If not OK, repair the open fused front blower motor relay output circuit to the IPM as required.
Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Disconnect the front blower motor wire harness connector from the connector receptacle of the front blower power module. Use jumper wires to connect a battery and ground feeds to the blower motor wire harness connector. The blower motor should operate. If OK, do the Body Diagnostic Procedures. If not OK replace the faulty front blower motor.

let me know

I'm not sure you're willing to do the work yourself on this vehicle. If this is the case, you should pay a visit to your local community college and speak with an automotive student.

If your issue can't be remedied with the simple replacement of a fuse, then it's most likely your front blower motor has failed.

This is still an easy fix, but a shop will charge you a lot. But if you can locate a student, they'll certainly do this for half the cost, and maybe less.
