When I on the key on my 2008 I hear 8 to 10 clicks that seem to be coming from under the dash on the passenger side. Everything runs fine and the heater works. I do seem at times to smell antifreeze but I'm not losing fluid and not overheating. Any ideas?

 

The mode door is trying to calibrate itself. Probably a bit of the insulation came loose.

 

It could be the blend door, check the cabin air filter, perhaps get a new filter.
