Power window switch taking off question.

Hey, I bought a few things at Home Depot. Granted it was right around the corner and the easiest place to try. Great for 5 gallon buckets to drain oil into, pre-cut lengths of pipe to use as breaker bars and I bought some Husky metric sockets in a pinch.

Hey guys, I test it 3 days continuously to see what is going on and I found that when it hot, it won't work, but it works fine when it's cool down.
The passenger side is stuck, so it completely dead.
The driver switch for the passenger window is working when it's cool, as above. Morning works fine. Middle of noon, it's dead. Night, it works fine. I just tried it a second ago and it works fine.
Driver window is fine.
Anyone can think of which component is the problem maker? Some relay can't take the heat? It get over 100 degree inside my car at noon.

After it off, I found that it is an OE porsche switch. It was hard to open it up to see the internal but at the end, I did. The cause was heat. Heat melted one of the plastic pin and made it shorter, also some internal chambers were melted too, those jam the copper blade; which won't allow the switch to flick. Instead of waiting on part order, I cleaned up all melted parts and made a pin by a big nail.

The question is why it melted, is there any other component\s which is going bad? Well, look like it is in working order. Summer heat? Can't be. My buddy explanation was corosion. Corosion can generate heat. Ok, I cleaned it up well using a lot of WD40, and re-crimpped all crimps well/tight. Let's see.
