Heater problem
1998 Jeep Wrangler 6 cyl Four Wheel Drive Manual

Heater vents only through the defroster in any selection of the control. My vehicle only has a heater unit no AC. Heat comes out fine. I replaced the heater control assy. What else can I replace?

Hi sfcjdherrera, Thank you for the donation. Check the vacumn hoses. Loss of vacumn hoses woulnd not allow the vents to operate correctly.

Check the temperature control cable and blend air door movement.
