Hot in the back - ice cold up front!
I've got an 99 S430 (long wheelbase in the UK - I think they are all Long in the US).
The rear heater controls when turned on pump out hot air even when set on the lowest (16 degrees). In turn the front then compesates and turns up front into a freezer.
Main agent swapped the duo-valve (Heater control valve - Sp?). Result - Full day at the dealers - 450 dollar bill - no change whatso-ever.
Any one else had this - any ideas.
Latest dealer claim is it must be wiring! They apologised and are arranging to have it back in.
