superbee Posted December 23, 2008 Share Posted December 23, 2008 My heater blows warm air all the time, but it doesn't always come out the desired locations. The defrost is the hardest to get it to switch to. I even left the control alone after getting it working good on floor/defrost. Then after shutting the truck down and restarting it, it went to floor only. What could it be? Link to comment Share on other sites More sharing options...
