Greetings,
All four door locks and all four power windows suddenly don't work, either by keyless remote or by manually pressing the doorlock button on the door. Curiously, the side-view mirror control buttons on the driver's side door console DO work. The keyless remote does activate the trunk lid and when I press unlock, the lights do activate at night. However, there's still no response from the doorlocks. These things all went out simultaneously.
This sounds funny, but the exact same time this problem occurred, I noticed what looks like rat droppings began appearing on the floor, both in the driver's section and the passenger side. (My area, Marin County, a mostly country-like suburb just north of San Francisco, is experiencing a rat epidemic of sorts.) I also noticed what looks like wiring insulation under the driver side dashboard that had been knawed off and bits and pieces fallen to the floor. In addition, I found a small piece of wire with purple insulation that looked like it had been chewed loose and that, too, had fallen to the floor on the driver's side under the dash.
I had examined fuses as the Buick dealer recommended; however, they all looked OK.
I believe it might be a probem with rodents getting into the electrical wiring that disabled the power windows and doorlocks. My family and I are very careful to leave the car clean and not leave the door open unattended for any length of time. And I have carefully searched the interior of the car, looked under the seats, and even pulled the rear passenger seat cushion off to examine for any rats nesting inside the car. I even checked the trunk for good measure. They don't appear anywhere at the time I search, yet, when I come back the next day, there's rat droppings on the floor again, although the car is locked tight at night. It is a mystery to me how they get inside.
My questions:
1.) Is there a way a rodent could gain access from outside though an opening, vent, etc., and if so, could a screen or other device be installed to remedy this problem without causing harm to the vehicle's functioning systems?
2.) What would be the best way to access and examine the wiring/electrical contacts for the doorlocks/power windows in a 2003 LeSabre?
I searched the Buick LeSabre forum, however, I did not find a specific answer for the power system related to the 2003 model.
Thank you so much for your time and help. God bless you.
