1998 Explorer 4.0 SOHC and the thin grey vacuum line from the heater control valve broke and I have no heat. Before the actual break, i did not have heat, so I checked the control valve with vacuum pump and it works fine. Then I thought to trace the line back and do the pump again to see exactly where the issue was. I thought the line went to the vacuum ball (Right front fender) and it does not, but I think it goes to the fire wall under the dash. Here are some pics of what I'm talking about.
The broken grey line
Then it goes under the blower motor or AC, or whatever it is and disappears
Then under the glovebox at the fire wall this is what I see. Does the grey vacuum line connect to the lines right at the firewall (on the other side maybe), or??
Trying to find this info is like looking for the Holy Grail...Any help would be appreciated...Ed
