Hello everybody in my first post.
I need some help with my sunroof. I have a new switch in it, so I don't know what happens. Sunroof sometimes works, sometimes don't. Now, with the new switch, I can see the light of the switch when it works, no light when it doesn't work. So maybe it's a electrical problem, but where is it??... The sunroof seems to works better in colder temperature (at night for example).....
Any opinions???

First, did the sunroof work all the time before you changed the switch? If it did, then you have a faulty switch. But if you replaced the switch because of the same problem, then it could be the wiring. I would lean towards the sunroof motor.
The sunroof motor is similar to the operation of a power window motor. When the motor is failing or is overheating, there is an internal switch that cuts off the motor and once it cools down, the switch closes again so the window could be closed.

Intermittent operation of a sunroof or power window usually point to the motor.

Just a suggestion!
