I too am having this issue. I have no recent battery swaps or power issues. Mine seemed to happened after I switched from a/c off to a/c on now no a/c on my side(drivers). This is very difficult to deal with since the passanger side does not blow enough to cool the vehicle. I have little luck when It comes to dash issues but also may have an a/c leak problem and not knowing where it is coming from hopefully not the evaporator which I believe is in the dash of hell. So any recommendations would be gladly appreciated.
