Howdy folks. I recently bought a 2000 ram 1500. I'm having a problem that I hope isn't one of a kind. When I'm driving down the interstate, pulling a hill, or anything else that puts a load on the engine, my heater will switch from the vents to defrost..... Anyone else have this problem? If so, did you figure out how to fix it? Any help would be greatly appreciated.

 

Try a search here for wild vents, cheap ez fix, 10 min work to fix it.

Thanks. That gives me a place to start.
