Hello everybody!
I have an e34 with automatic climate control and about 2 weeks ago the heater stopped working properly.When i set the temperature to 16 degrees celsius on the passenger side the heater keeps blowing hot air.On the drivers side i think it works like it suppose to. So far i checked the water valve connection, there are 3 wires: yellow, yellow+purple and yellow+brown, when i turn the rotary switch temperature i get 12v between : 1) yellow and yellow+purple , 2) yellow and yellow+brown.
Meanwhile i found out that one of the circuit components is broken, the code is : L575A ST 94A214 it's a integrated circuit with 8 legs, does any one have any idea what this thing does; where can i find the data sheet ?
