OK, I think it is a red line with green stripe. The stripe color is hard to see. The a/c blows good out of the vents. But when I try to swtich to heating I can't get hot air out of the dash vents and when I swith to defrost it won't move for the longest time if at all.
So I guess I need to look into the dash for a leak. Sounds like quite an adventure. Any tips on looking for vacuum leaks in the dash area? Thanks again, Ken
