2003 Cadillac CTS

Dear Doctor: I own a 2003 Cadillac CTS with only 27,000 miles. I recently replaced the battery and encountered a problem with the power windows. When I push the power button to have the driver’s window go down, the passenger’s window also goes down. The same happens to the rear windows, too. They all worked fine before I replaced the battery. What is making this happen? Will
Dear Will: Most new vehicles have logic modules, body modules and door window modules. These modules are all subject to confusion when battery voltage is interrupted. I looked on our Identifix web site and found the same condition noted from another technician. In this case he disconnected the battery for one hour. This resolved the problem.
