Need a Power Window Control Module - help

[my96cab]

Hi all-
I hope someone can help me. I am in dire need of a Power window control module for my '96 Cabriolet. The module I have in there now is not the correct module for this year Cab, but partially working. It is from an earlier Cab and won't roll down the driver's window with the 'all down' switch. The Power window control module, that I need, is located under the dash, next to and to the left of the steering column, just about knee height. It is the module on the right of the two larger modules on that panel. The P/N of the Power Window Control Module is: 8GO 959 257A .
