Well here I am again talking about my Grrrrrrr Heating.
Symptoms are, Both passenger and Driver variable heat controls (Red/Blue jobs) need to be on full cold at all times, just one millimeter towards the Red and I cook. Now even with controls on full cool (Blue) I'm getting heat out and have to have all three slide vents (foot, face, screen) closed. So far I've changed the Matrix and the Heater control value situated in the engine bay. What else can it be ?. I'm now drawn towards the control panel itself, as it's electronic as I guess sends the message to the control valve to shut of the hot water to the matrix. :? Dose anyone else have any ideas before I fork out for a new one ? ------------- Andy, from www.bmwland.co.uk E34 525i Sport E28 528i

i think that there is a heater flow filter under the drivers side panel thats the panel that goes from the edge of the dash down to the pedals hopefully someone on this site might be able to help you more good luck ------------- E34 M30 535i SPORT

It sounds very much like the climate control unit is knackered rather than the matrix or the cables for the vents. The dial type knobs are soldered onto a PCB within the heater cluster which could have any component on there burnt out. I personally would go at the electronics with a multimeter and test the variations in voltage as you turn the knobs round. If its broken (i.e you dont see any change in voltage past the 1 notch) get one from a breakers and replace yours. Russ ------------- http://www.deathace.net">
