I have a 2011 jeep wrangler jk and there is no heat on the driver side. It only blows cold air, however the passenger side closest to the window blows lava hot air and the other vent on the passenger side is still hot but not as hot. I was able to look under the driver side and see the blend door move when i switched the temp from hot to cold so i suspect the blend door is not the issue. I would rather fix this my self then get the run around and rob at the dealer to fix it. Any suggestions on where to look next?
