My AC/Heater blower will work fine for anout a 1/2 hour and then it seems/sounds like it is switching from blowing air inside the cab to the outside up front soemwhere. It changes speeds OK. But no matter where I have the position switch it just blows outside until you let it sit for a long time and it will be normal for about a 1/2 hour then switch again. It did this in the summer with the AC and now in the cold with the heater. Any Suggestions!!

Sound to me like a gate valve in backwards. Or maybe , wired backwards. Door installed incorrectly.Heater/cooler tubing routed wrong.
