I've got a 2003 2wd Dually with the 5.9 High Output Cummins and 6 speed Trans. My problem is that when I try to change the vents from Dash to Foot or Defroster (or any combination) they don't change, it just keeps blowing out the Dash vents. I can turn the blower off and cycle the vent controls all the way in both directions and sometimes it will cause it to switch to one or the other. Also, the Hot/Cold switch has the same problem. It will be blowing cold air but I can cycle the switch several times back and forth and finaly a hear thud sound and it starts to blow warm air. I've been told it was caused by a vacuum leak, then I took it to guy who supposedly knows about these things and he said it was all electric and that my truck doesn't even have a vacuum pump on it. My questions are this:
1. Do my climate controls run off vacuum ?
A. If yes, then where the h@#l is the vacuum pump ?
B. If no, then what do you think is causing my problem ?
Any help would be appreciated. Thanks.
