does anyone have a dodge 1996 1500 service manual, one of the vacume lines that goes from the intake manifold in through the firewall and i think into the heater box broke. it is 1/8 flexible black hose. the heater does not blow hot,warm air. and switches back and forth from place selected to blow floor, defrost, direct on passangers.
any guess would be appreciated and if you know were it goes. ill try and upload a picture if anyone has a similar truck, it is a a/c 5.2 1996 1500.
