I didn't see this question posted any where else , so I figured I would post it here
I have a 2007 Ford Edge , I don't have dual climate controls , just the single control for both sides. I had the heater core cleaned and flushed out 3 years ago , after having no heat , now I have heat only on the passenger side , I was told by my local Ford dealer that the Heater core needed to be removed and cleaned out , I could see this if I had no heat on either side , bit with normal heat on passenger side , I don't see how this is possible ,am I correct on this ?
