Hey paBullwinkle,

It's not the best but try, "http://www.autozone.com/autozone/repair ... 528006c5de" . This is for a G series van which is the same as the P. Hope it helps,

Doesn't show it all but its a dang good start.. let me explain the issue and maybe someone in the forums can help. In the line that runs to the pcv valve theres a splitter that gives me anonther vacuum connection but the problem is that theres no vacuum line there but instead theres a bolt stuck in it to plug the line. Aswell as the heater air control to direct the heat/ac to a different location and the AC compressor wont kick on. theres a vaum line under the dog house that goes somewhere but where i dont know yet. i am going to have to trace all these lines and see where each one goes.




Respectfully,

Well good news i got it fixed. found that that vacuum line that went to the vacuum bulb was off the manifold. fixed that and it started work. The Chevy garage musta knocked it off when they did the tune up on it. Now i gotta figure out why theres two vacuum lines going to the Vacuum canister for the evap system.
