Resolved Question:

I have a 320d tourer e91 and the climate control has just stopped working. There are no lights or power to the whole system, so cannot demise the rear screen, as well as this the button to switch the parking sensors on and off doesn't work as well as the auto start/stop button, they are all on the same system. Plus the 2 lights in the boot stopped and the tail light all other electrical systems work and there are no warning lights showing on dash.

sorry for the delay - so you yourself have not checked anything yet either?

Customer: replied 1 year ago.
The only thing I have checked is the fuses and all of them are ok. As I said nothing on the dual climate control screen/display lights up and none of the buttons on that section of the console light up or start any type of action from the a/c, heater demister.

thank you for your attention to the rating requirement.

I have reviewed the wiring diagrams for your car carefully.

.

the likely cause is an issue with the JBE which is an electronic control module fitted to the fuse panel. This is common to the components that are not working (these cars are known for overheating of the fuse box). It is also possible that you have a wiring or ground issue but that is less likely. The JBE would need to be replaced if faulty.
