Thread: Heater trouble

Hi all!
Now as the cold season approaches I came to notice that the heater only gives effect when you turn the dial until the last third of the range. The initial two-thirds don't have any effect at all, i.e. the incoming air is not heated. Both sides are equally effected.
I have changed the coolant some months ago and bled the system accordingly. Is it possible that there still might be some air trapped in the heat exchanger? If so, how do I get rid of it? Anything else that can explain the symptoms?
Any help appreciated!
Cheers

Usually the reason for "non heating heater" in our Discos is bad bleeding, but, if you did the bled work in the correct way last time, I can give two other posibilities to you:
- clogged heater (you can check it by undoing heater hoses and passing water to check it)
- losed heater control cables (may be the cold air duct isn´t closed and there is too much cold air in the mix)

Scuse me for my neolithic expressions. My language is spanish
