I have a 1997 Ram 1500 extended cab 2WD with 360 V8 and the cruise control doesn't work. I have been told that it is a vacume line and if thats the case, could someone please tell me where the line may be located? Also, when i have my A/C on with the vents switched to the position when they blow straight out into the cab of the truck and i accelerate, the air stops blowing through the front vents and begins blowing through the vents in the windsheild. Then when I let off of the gas, it goes back to normal. Any ideas? Maybe another vacume line? Maybe the same one for both? Please help!
