Heat not properly working
Hi guys, I have an 83 z28 that is a factory non AC car. I have the 3 selectors: vent-heat-defrost. On all 3 of these, the 3 speeds work fine and I can hear the change. However, on the heat setting, the air is being redirected to the defrost vents and no air is coming through the heater vents. Any thoughts? Vacuum issue? Thanks!

Re: Heat not properly working
I pulled the unit forward to check for a vacuum leak at the switch but I dont see anything resembling a switch with vacuum lines or anything of the sort going to it...
