Hi guys! SInce last winter my heater has been on the sorry side of luke warm, and the heater fan is working more and more irregularly as the temperature drops. The shop said the T-stat was wide open, so that was changed. I now get the temperature needle to 6 o'clock, but not more, so in cold weather the air is luke warm. What is worse is the heater fan. The colder the weather, the more unstable it behaves - below 15 celsius there is nothing happening, it is just dead. Which is a bit annoying, as I sometimes go for 5 hour drives (with the family) in -20 celsius and colder. The heater fan motor is also brand new, so is the switch, but the problem persists. Any takers?
