Hello all,
I have a 2007 Ram 1500 5.7L. My heat is coming out of the defrost vent. The selector will change it to mid level vents, but will not direct to floor vents. Any advice for a fix?:shy:

I realize this is an older thread but here's an answer for ya anyway.

Sounds like your problem is very likely mode door 2....not mode door 1. MD1 simply diverts air from the main front vents to the secondary part of the system. MD2 is the one that decides whether the air goes up to the defrost or down to your cold toes. MD2 failure is common on these trucks and unfortunately is the most difficult to fix. Heatertreater does make a kit but a large part of the dash still has to be removed to access MD2. Per Heatertreater....."Most people choose to wear two pairs of socks than to replace MD2."
