Hi All, I recently replaced my heater core in 2000 Ranger and while working uder the hood, the grey vacuum line that leads to the interior of the truck browke . For the life of me I can't find where the other end is.

Does anyone have an Idea?

It one of 2 lines that lead from the engine compartment into the cab to control the A/C and Heat and its Grey in color.

 

The gray vacuum hose is connected to the heater control valve. If it broke inside look at the white vacuum hose going to the recirculation door, it could be spliced off that hose.

 

Thanks harley9701. Its broken outside in the engine compartment. It is connected to a modular splice leading into the cab located on the firewall and under the AC Condensor and fan. Im looking for were it went on the engine side.
