The components listed above have been replaced....

I originally put new main pump on which started whining after a week of driving and got hot and quit. I just replaced both transfer and main pump and after idling about 10 mins the main pump got hot and started whining. It will go away after a few seconds and pump will cool then start heating up again and whine. I replaced both pumps with quality parts. I don't know where to go next

How can I tell if my 1993 Classic Collectors Edition has California Emissions or not.

I have a problem with my friend's Cabriolet where the automatic windows on the side doors will not go up or down on the car when you press the switch. My friend says that the motors for the windows check out (he works on cars), but he says that a specific piece called the "celluloid" or "cellanoid" (not sure if I have the right word) needs to be replaced. I was wondering if you could help me diagnose the problem.

Does the piece go under a different name - like a "window regulator?" Is that the same piece? Is it a different piece? What do you think the problem might be? Have other '93 Cabriolet convertibles had the same problem?

Thank you, everyone, for your help :) I look forward to hearing from you soon.

Take care,
