2013 Buick Encore Premium 4dr SUV (1.4L 4cyl Turbo 6A)
on short trips at 25 below c. the heat gauge comes up to normal then when you turn the fan wide open the heat gauge goes back to cold
and blows cold air on highway driving works ok
dealer put new thermostat in still same problem returned to dealer who phoned gm and was told there seems to be a problem with heat has anyone else had this problem
Have '14 Encore, when heater control is on defrost/floor heat with fan at full tilt (driving speed makes no difference same at 55 as 25mph) Windows will not stay clear and your feet freeze! Going to dealer this week! All other heat settings work fine.
