Greeting, my 2008 edge SEL no longer has heat on the driver side, passenger side if fine. When I first turn the heater on it seems to start heating on the drivers side but eventually stops blowing hot air. Car has < 100k and I had the cooling system flushed and replaced on a recall a few years ago and there was no problem then. With an ambient temp of 78 degrees the passenger vent registers 149 degrees while I only register 107 on the drivers side. With A/C on both sides register 46 degrees. I have read a number of write ups about this problem but I can not recall any of them mentioning if the problem was fixed and what they did to fix it. Any ideas? Thanks Gary
