I have a 2004 CL500 that recently developed some electronic issues:
First the windows (all of them) would not work. No down or up. Then a day later they would work. I left them up because I was afraid they would not work again.
At the same time the seat controls would not work then hey would.
Then all the lights in the cabin came on by themselves eventually they did go off but the te strangest part happened.
Warning lights for the brakes came on and stayed on. This while I was driving. I checked that the brakes were working and fortunately they did.
While I was driving a message appeared on the "Message Center" saying something to the effect there was no connection to something and it went blank.
Also all the little lights for different accessory control;s lit up and I mean all of them.
The car starts, drives and stops as normal but its like the car is possessed and needs an exorcism.
Which electronic module(s) do you think is at fault.
Please I need help urgently I need to get my car back on the road ASAP.
