Hi guys! I'm a newbie - be patient with me! I have kinda a weird one. Got in my truck yesterday after work and the drivers side vents were blowing heat and the passenger ones were blowing AC. I checked everything - I have the dual zone thing where it can be set differently for driver and passenger, and it was all the way down as far as it could go on both sides. I turned it completely off, and pushed the recirculate inside air thing on. Drove about 15 miles, was in a store for about 30 minutes. When I came back out, the AC was working perfectly on both sides! BUT - the check engine light was on too! I unhooked the battery cable last night just to get the light to go away, but does anybody have a clue what this might be?? Any help would bemost appreciated.........THANKS!
