climate control center blank

Check the BCM probably bad, needs replaced. behind the glove box

It is not the BCM I have the same problem. I replaced the BCM and it did fix the speed and upper dash but not the fuel or Climate control center

I just had mine repaired at Cadillac dealership. My electronic climate control and fuel sections went blank. They had to replace with the BCM computer located behind glove box. The 1st replacement didn't work...2nd one fried up...the 3rd one worked like a charm. The total cost was $544.00. I told them of info I found in here about the BCM...but after a days work of trying to diagnose and no results...they went with my idea. Wallah it worked. If they would have taken advice it would have saved me $300.00 in diagnostic cost. Good Luck , Mac
