Air conditioning heating problem
Troubles with Euro WH HEMI MY2007 (bought December 2006).
A month ago, heating wouldn't work. No warm heating, even though setting the heater to "HI" and using manual heating (no auto).
Service technician told me it could be due to:
- faulty infrared sensors, although no error from diagnostics
- faulty heating radiator (needs dash removal = $$$$)
- Coolant leakage
As the coolant level was between the MIN and MAX level, the level was refilled up to MAX.
The heating started working again!
However still there's something strange:
- In the first minutes of usage, the air flowing is very hot (HI & manual)
- Once hot enough, switching the temp to 22/24 cools down the air temp
- When switching again to HI (& manual) the air will not get hot anymore...
- The coolant level did not change (no leaks)
- As the infrared sensor should be inactive when in manual mode, it shouldn't be taken in account.. correct?
What can I try? Maybe some air somewhere? Or could the heating radiator be defective?
