hot rear air condotioning

Postby caneda » Mon Jul 02, 2018 8:03 am

Hello,
I own an Euroline MK6.
The front A/C works well, but the rear A/c dosn`t, the air is hot.
The famous heater blend actuator is new...

Air in back blower all the time is going through heater and AC evaporator.
Heater is controlled by electric valve using PWM signal from special electronic unit. If the whole time valve is opened, you're getting blend of warm and cold air...
So - it can be blocked valve in opened position or his electronic circuit doesn't work. Broken valve is the most probable reason - especially if warm air is going from upper vents.

On the picture - red circle - valve, blue circle - electronic PWM valve module.
