Ever since I have had the X5 I have had a few dead pixels in the climate control. My E39 which is 8 years older has a perfect climate control. Unfortunately the E39 has the "rest" button and the E53 has the "max" button. Anyway, I pulled the 2 units out to see if I could swap displays. Turns out even the display circuit board is laid out differently so I put them both back together. I did however remove the display from the X5 and clean contacts to see if it made any difference. When I first put it back, the display was all blotchy, so I pulled it out again and realigned everything and put it back.
Now nothing works. All the buttons are lit up, even with ignition off and the fan is operating and blowing some air out the vents. Pushing any buttons makes no difference. To make it worse, the display does nothing apart from a little bit of backlight when I turn on the ignition. I checked it with INPA and with PA soft and no errors.
Any ideas?? Pic below.
