MY 86 735i HVAC control panel is dead, I have checked all pins into the thumb wheel board and the push button board for power. This is what I get:
- No power at all into the push button board.
- Pin #16 (red/green) on the thumb wheel board has 6 volt.
Can someone has an ETM help me out? I have checked all fuses and switched the 2 relays at the blowers but does not get anything.
Thanks for all helps,
