My truck has the standard/manual climate controls. the 1st dial on left (fan level control) has 6positions, off and levels 1 thru 5. Problem is that only the highest one (level 5) works. Levels 1-4 stopped working gradually, one at a time. I checked all the related fuses according to the owners manual and they are fine. I also purchased another whole control unit from ebay. After switching entire units, the problem remains............please help!
