OEM wiring- has full power running through the switches- the contacts are subject to arcing and the voltage drop will not let the motors work at their best. So replacing the switches that are of a better quality really don't solve the problem.
Using four Bosch relays to control the up and down - the motors will run faster and the switches will last forever.
In pic- Right side -the relays have been added- left side is OEM wiring
I'm actually running Jaguar (Lucas- the prince of darkness) switches in mine with relays!!!
Well I learned something new. Never crossed my mind to install relays for faster power window operation. I’ve ordered the micro relays and bases for my next project.
I know this was 6 years ago, but wondering how your switches hold up all those years?
i’m willing to try your mod! Getting tired from faulty switches. Your feedback would be appreciated.
Thank you,

Yes, they have held up very well. No issues at all.
But, I do have to tell you that I've since upgraded to using relays like Richard described. I didn't do this because I was having problems though. I did it because I had some of the interior apart for another reason, I had some extra relays, and just thought I would do it while everything was exposed and easy to access.
