No heat ,unless on interstate at 75 mph ,45 min into drive, none in town.

What is your question?

I have no heat oddly enough the only time the heat will kick on is if I am on the interstate doing between 70 and 75 mph about 45 minutes into my drive in my commute. But around town I could go from the East side to the west side and it never warms up.

What makes this problem better or worse?

No heat around town ... Only heat 45 minutes into the drive doing 75 mph

How long has your 2003 Jeep Liberty had this problem?

Just started this year
