W210 E320 CDI 2002 Air Con/Heater Question

[Rana]

Hi,

New to a July 2002 68K E320 CDI Estate Elegance FMBSH....with supplier warranty.

If the Air Con is on and both temperature wheels are set set at 'white' on occassions I get Hot Air blowing at the driver side and cool are blowing out the passenger side ?

Any ideas on the reason behind this i.e. is it expected behaviour ?

Also now the left hand temperature dial, the fan speed and heated rear window are no longer illimuniated but work fine ? Or is it the Heater Booster System kicking in ? this is in automatic mode.

Do Service B in 800 miles.

thanks in advance for any comments

Eventually the dealer has agreed that it is the duo-valve having already replaced the water heater !

Watch the air con, the condenser radiator is a weak point and is expensive. Make sure you are getting fully cold air on both sides quickly as it may indicate a failed rad. Its under the cover behind the front passenger side wheel arch.
