SOURCE: how to replace a blower motor resistor in a 2004 jeep liberty

I'm not 100% sure where it is, or possibly built right in to the dash control/fan switch, but I'd be tempted to stop & see the parts guy at the dealership, or another dealership, and ask if they have one, or a picture of one. Once you see it, you'll know where to look. Just a guess but quite often built right into switch on dash.

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

replace the turns signals flasher unit.

SOURCE: my 2003 jeep wrangler AC/heat fan doesn't blow any air out.

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.
