For all the people mentioning the use of a fuse when I posted this thread, yes your right, I forgot to add that bit of information in. - But I did mention that it's better to use a relay, but this is a quick fix. I have 20 amp switches running 15 amp wire, that is all that is required.

When you start upgrading to 30 amp cable it's unnessesary, as the original wire supplying the whole cars power can carry a max of 15 amps, so 30 amp is overkill just for the windows. I ran some 2.5mm 240V single core cable to supply the switches. And if a switch burns out under less than 15 amps of load, then there is a problem

(The 30 amp fuse allows both switches to operate at the same time, which means each individual switch can run at a max of 15 amps)
The constant arcing when the switch is used causes the contacts to carbon up which slows down the windows. In all honesty, relay's aren't perfect either but the contacts close a way quicker so they last a lot longer. Solid state is the way to go.

Well 90% of the people I have met HAVE had this problem.

And yes I have had that problem too, I thought it was someone slamming the door too hard, but my mirror aims fully down too. Is that a common problem?
