Electrical problem
2005 Buick La Crosse 6 cyl Front Wheel Drive Automatic 27000 miles
----------------------------------------------------------------
The alarm system comes on in the middle of the night and honk/flashes off and on for hours. the sounds are irregular, sometime 3or4 honks, pauses, honks again for l minute. Tried locking and unlocking doors to disingage. Twice to the dealer, never honked there (I belive the disengaged the theft flashing light) but it has to be stopped using the key pad - will start honking again after a few minutes or maybe 30 minutes.
