Q: Useless heater, live in a cold region

asked by on November 06, 2015

The AC in my 2008 Jeep Wrangler has never been great and I have always accepted that as a Jeep quirk. Now I can barely get hot air out of it in the winter! That’s when I need the air, the roof is off all summer. This truck has 75,000 miles on it and I want to keep it for the long haul. What is a good way to repair this problem once and for all? I need the heaters to defrost the windows in the winter.
