Hope somebody can help me, i have a 1997 328i. My temperature control unit is making me blond. When i switch my car on, then all the lights is dead, when i unplug the plug at the back, then my fan goes on. But when i put the plug back just half way then the display and the lights is on and the unit is working 100%. But when i lock that plug then the display and lights goes of. Please help me. Thanks in advance Leon
