Thanks for your help. I have discovered exactly what you have said, there is no homelink GDO for my car. I went to the homelink website, they have a list of the cars that have the GDO option, to my surprise, Pontiacs are not listed! Funny you should mention the Monte Carlo. I have one of those also, it too is a 2002, and it has the GDO option and has a sunroof. So, I guess I'll look for the electronics from a donor car, and see if I can adapt and install it in my GP. I also own a 1996 Riviera, it came with the GDO option from the factory. But pre 1998 vehicles use a different GDO code system not compatible with newer garage door opener electronics. Since the '96 thru '99 Rivieras had essentially the same interiors, I bought a GDO panel from a salvage yard for $25 from a '99 Riviera, it was an exact replacement to the '96 panel. Installed very easily, and bingo, my '96 now will open my garage door! Have to figure out something for my GP. If you have any suggestions, let me know. If I figure out a nice neat way to make it happen, I'll post to GP forum. Thanks again!
