Well the truck is a 2002 E53 x5. The sun roof tray was leaking into the passenger footwell. I took out the entire interior, including the headliner, and repaired the leak. However, I made the BIG mistake of reconnecting the battery to open the sunroof with most of the interior components unconnected. I actually saw all the lights of the cluster come one when i connected the battery. Well to make a long story short, we now have the issues with the signal lights working from outside but not through the cluster. No high beams or any other instruments working in the cluster. However, the tach, temp gauge, speedo, gas gauge all work fine. Also, reverse light does not work. Other that that, all is fine.
