So the past couple of weeks I have had an interment issue where the heat would only come from defrost. Since I do not have automatic hubs (replaced with Warn) I began to troubleshoot. I think that I found the problem right away but want to validate. From the Vacuum pump the line goes to a connector attached to another box. There are 2 lines from this box one goes to the cab, the other to a relay then to where I suspect would be the front hubs.
Anyway, I disconnect the vacuum connector from this box and I have vacuum from the port. If I "jump" between the two ports, I get vacuum throughout the system (heater works properly). So my question is: Is this box a vacuum amplifier or something? Also I suspect that it is bad, does anyone know the part number for this thing?
