Heater problem
2005 Jeep Wrangler 6 cyl Four Wheel Drive Manual 139.00 miles

My heater will only work on the defrost selection and not any of the outher selections with the switch.

Hello and thanks for the donation!


This could be caused by a vacuum leak in the vacuum lines controlling the blend doors or a faulty blend door actuator. You will need to inspect the HVAC system thoroughly behind the dash to find the cause of this issue.
