how can i fix electric window switch?

If it's the 6 button swich, they're £150 inc vat from Peugeot, so not cheap at all. On the same unit, try to find someone who can swap your nearside rear switch for your drivers window switch, (you will probably have used this one less) and it should have a couple of years life left in it. I mean swap the switch that the driver operates, not the actual switch on the rear door, if that makes sense.
2nd hand ones are not much better than useless. I've had 2 replacements now. 2nd hand ones range from £30 to £70. Get someone to swap your other switches round if you can.

Switches in cars are usually beyond "fixing" when they fail - the sensible approach is to buy and fit a new switch.

Your window may be stuck because of a fuse failure (doubtful unless each window has its own fuse) - the switch which you suspect - the winding motor - the lifting mechanism.

I have had two electric window failures - not on a Peugeot - and each of them was the winding gear. I had a mobile car lock specialist sort it out each time - £50 parts and £50 labour.

Let's hope it's the switch - much cheaper replacement cost and easier to do.

Good luck...
