Heater problem
1992 Volvo 740 4 cyl Two Wheel Drive Automatic 160000 miles
We recently replaced the heater core after a garage had removed the leaking core from the system (bypassed). They removed the heater control valve which we now want to re-install. We cannot find a vauum line to drive it. Where can I get a diagram of the vacuum lines in the car?

this is too old a post to be worthwhile, yet someone else might be looking for the same answer. So, look into the VACUUM harness that attaches to the ACC or ECC and one of the tubes should be the heat valve vacuum connection
