2008 Lucerne HELP

[Darkbrad82]

Drove home and all was well. Got in and started it the next morning and i have service stabilitrack, service abs, service lane departure, park assist unavailable. Brake lights constantly on. Soni changed the brake light switch. Didn't help. Then pulled codes. Says right front abs sensor, invalid circut from abs pump. Brake lights still on all the time. And now back locks and windows dont work from thier control or the main control or the fob... At a loss how this can happen overnight. Love this car and want to keep ot running. Please help!

On the ABS you may have a harness, connection or wheel hub sensor that may be the issue. Check the connections and harness is probably the first thing to confirm, if you were able to identify the right front hub it may have gone bad and the hub sensor doesn't really give much notice.

The first place to check on the rear windows is the driver's door master control as they both work through it. It could be the MC or wiring harnesse which you may try a continuity test between the drivers door and a rear or voltage test on the rears to confirm they are or are not getting power. Just make sure the window lock is off, sounds funny but I've fixed other peoples vehicles by turning it off and a chuckle.
