Air Conditioning problem
1985 Chevy Monte Carlo 6 cyl Two Wheel Drive Automatic 157000 miles
ON THE BACK OF THE CONTROL PANEL THERE IS A VACUUM POD WITH MULTIPLE LITTLE VACUUM LINES ATTACHEDTO IT SUPPOSELY TO CONTROL/DIRECT THE HEATING AND A/C AIR FLOW. ONE OF THE PORT IS MISSING A VACUUM LINE.
IS THE A DIAGRAM THAT SHOWS THE LOCATION AND ROUTE FOR EACH OF THOSE LITTLE VACUUM LINES?
Your local library usually has repair manuals or your repair shop may provide you the info.
Is there a problem with the controler? The lines are incased in a clear plastic plug that attaches to select switch not all are used so if it works in all modes there may be no need to track down every line.
