I've been having problems with the front and rear power passenger (right) side windwows. Occasionally they operates but mostly don't.

The rocker switches (F&R) lit, so the current must be passing through. My first suspicion is that the switch must have bad contact, but I wonder how this can happen to both both F & R? The probably cause then appears to be that the switch may be bad. Therefore, I tried using the driver (left) side switch which is good, to power up and down the malfunctioned windows. Surprisingly, this doesn't work either. After all efforts, I restored everything back to the way they should be, the malfunctioned windows beccame operational again. The cold front is coming so I decided to leave them alone for now, but I am puzzled...

My questions: is there a kind of chemical I could apply to the switch and the plug to make them more contact sensitive? Can the driver side switch work on the passenger side switch (given that the driver side switch has a locking mechanism which I did not unplug)? Is the most likely that the problem can be solved by replacing the passenger side switch with a new one?

Thanks for any assistance you can provide.
