Hey Guys,
New member and glad to be here. Our boss has a 1990 v1500 Suburban. It is stock and seems to be working OK, except for the following problem. When he turns the A/C on at at any speed the left hand and right hand vent blows great, but the center vent does not blow at all. Air is cold from the vents that blow. I do not know if he has a rear AC system, it was not mentioned. Any of you guys work on these or have the shop diagrams for the manual heater section and or the air handler duct system that would be great. Or if you have personal knowledge of what the heck causes this dive right in.
