the heater only works at maximum temperature, one press to lower the temperature and immediately golden air. what could it be, has anyone encountered this?:желание:

 

Possible Thoughts:
- Heater Core Coolant Valve (cannot remember the correct name of this)
- Mix Blend Door
- Interior Temp Sensor

The first two you need to visually watch to see if they are moving when you change the temp control. The coolant valve is in the engine bay on the firewall in the middle. The blend doors you can see from under the dash. The temp sensor....I am not sure of...I know there was a thread in here years ago that described how to test that.

 

Your air mixer motor is not working.

 

airmix motor. you might be able to clean the contacts, otherwise need new. they are expensive.
