I’ve got a really bad short-term memory, sadly my car gets hurt because of it This time I forgot to return to the car after removing a stack of hot pizzas from it. When I returned to the car late that night, after some rain fall, water got into the inside of the driver’s side door. The electronics worked ok at first, but as I exited my driveway my driver’s side passenger window automatically went all the way down by itself. I put it back up, then it came back down, up, down, up, down, up, down … for about 1/2 mile, when I got to the store it refused to go back up so I had to babysit the car in the parking lot until it decided to allow me to send it back up again.
Today (a day later), I got in the car exited the driveway tested the windows, thought everything was OK because the driver’s side passenger window worked just fine, but 2 miles into my trip my driver’s window would not respond to the up command, then the other windows stopped responding to the driver’s window controls although they did respond to respective door controls. I arrived at my destination but could not close my window, it starting to drizzle so I just went back home.
I’m thinking the contacts on the mother board got wet and the corrosion was just waiting for me to open the circuit one last time so that it could finish frying itself to death.
Questions: Is there a test for this type of damage? What is the most cost effective way to repair this? Is there a spray (ie: silicone) that might get things back on track? Could I replace mother board or must I replace the whole keypad?
