2008 Mercury Mariner Question: the driver side blows cold air when it is set to warm
Answer #1Oakman October 23, 2009, 14:24Master
Chances are there is a problem with the driver side temperature control actuator. Your 2008 Mercury Mariner may still be under warranty for this. Perhaps a trip to your local dealer would be in order.

Seems that this is going to be a common problem for this model. Mine is doing the same thing.

I went to the dealership for this. I had this problems and audible clicking coming from the dash. They told me the air vent motor was going out and would have to be replaced. First response I got was this was not covered under warranty and would be $400 to replace.

Mine did the same thing on an intermittent basis. The problem was the blend-doors (Dual Zone Climate Control) which were replaced and now works perfectly.
