I don't know how the system works on your model.

I would check for proper cable attachment to the heater control lever inside the cabin.
Look at the adjustment of the cable that goes from the lever to the heater control valve.
Also, check that the arm of the heater control valve goes through its full range of motion.
If not - adjust cable

If everything checks out OK - high probability of a leaking heater control valve.

HTH!

Now, I really need to go to bed!
