Thanks again for your information about my windows. Got another issue w. My Bro's 2006 DTS. Headlights go out intermittently, sometimes together and sometimes separately.

Internet traffic suggests this is a very common problem, and to repair the headlights, the front bumper must be dropped slightly for the assembly to be removed, of course at considerable expense.

When the lights go out, they come on again if to move the switch from auto lights to manual, however they will go out again often at the worst time, very unsafe. Any suggestions?

Hello,

It sound like the BCM is going out. here is the headlight wiring diagrams so you can see how the system works and the location of the BCM, which will need to be programmed which will cost about $130.00. Here is a guide so you can help check the wiring to confirm the failure and diagrams below:

Check out the diagrams (below). Please let us know what happens.
