Thanks. A I just check, apparently the fuse for power window passenger side is fine. I guess the switch could be the issue ? any body ?
Try the switch on both the driver's door and the passenger door. If they both won't move the window up or down and the fuse test OK, then you have a bad window motor or bad connection at the motor.

I am not familiar with the Cayman but on the Boxster when you open door the window drops a bit and then re-closes. Does your's do this?? If it does then the motor is likely ok. If not, time to take the door card out and investigate. Rare but the actuator motor can go bad.

The motor seem to be ok , because it works from driver side but does not work only on passenger side.

OK, try this—
1 Using the driver's side switch, run the passenger window all the way down. Release switch.
2 Re-press the switch down and hold for 10 seconds. Release.
3 Repeat 1 & 2 with up.

Check passenger's switch. If it still doesn't work then IMO a faulty switch is likely.

Good luck.

Just to correct Gregs post above (sorry Greg) don't release the switch and re-press. Keep the switch pressed in the down position for 10 seconds then once fully up, keep it in the up position for 10 seconds. Remember to have the door closed at the time. If that doesn't work, it may be worth taking the doors switch out to see it the connector has come loose. Easily taken out with a trim tool.

No problems. :) The result should be the same.
The one I posted was taught me by the Service Chief at my dealer when he re-set the windows after a battery disconnection.
Good hint about investigating the door switch.

p.s. I've used the same technique to re-set the seat memory positions.

Seems like there are several ways to skin a cat when it comes to resetting the window travel: the one on the internet and the one in the owner's manual.
