Been looking at this one, customer had no problems untill battery went flat. New battery was fitted but noticed afterwards that windows,sunroof and mirrors did not work. All started to work again when battery disconnected and re-connected they packed up again some time later and stayed that way, disconnecting and re-connecting would not bring them back. Plugged in using DEC. No faults codes shown, live data in window system shows all switches at rest position and does not alter when switches are operated. Checked the lines from switch pack to BECM all ok,not sure what signals should be coming out of the electronic switch pack there are 3 control lines reading 5 volts which don't seem to change when switches are operated. Suspect the pack has gone down. Any help appreciated.
