Hello, I would like to see if I could assist you with this. You said that the left side only puts out slightly cool air while the passenger side is hot? Also, when you switch the temperature control from hot to cold (while listening carefully, it helps to have the blower on the slowest setting) you should be able to hear the mode doors switching from hot to cold.

Matt I don't hear anything.

OK, do you actually get cold air from the left side? Also, is this truck equipped with dual zone climate control?
