1997 Dodge Ram 2500 Q&A
1997 Dodge Ram 2500 Question: heat D.O. No suction at vacuum cable to heat controler. Should fingers feel.
Is problem defrost only? Are you working at the in dash control unit, or under hood? You say vac. cable,, you mean vac. tubing (*cluster of 5*) on back of controller,, or single vac. hose under hood? Really need to know this for a more accurate answer! - pushrod
have a smoke test done to find leak if you can't find the other end - globalhelper
