Title: Vacuum problem of an 02 f250
Post by: never_retreat on August 15, 2015, 07:21:22 PM

I figure there might be someone here that knows a thing or 2 about the 7.3L engine trucks.
I have a vacuum problem. All my a/c is coming out the defroster.
The little electric vacuum pump running I can here it, is there any good places to start?

Right rear of the engine bay. Look at the vacuum lines going into the heater box or through the firewall. They chortle the blend and diverter doors.
