Drivers side Window

My window is a nightmare to open, so stiff that i may pull the winder off one day, any idea how to loosen/fix.  i don't wanna rip the door card off and not have a clue what to do, any instructions welcome.
thank you

Is the window going up smoothly in the guides?

There could be a few causes:

1. The winder mech tube is full of dirt - clean it out and apply WD40
2. The winder mech tube is bent (from say an accident) - you could try and bend it back or just get a decent used one.
3. The window is not sitting correctly in the rubber channel on the winder - reposition in the channel by putting the glass in fairly loose and winding up to find the correct position by centralising itself. Then push the glass firmly into the rubber channel.

Either way the door card will have to come off but not too difficult. Make sure you have a decent waterproof membrane before refitting the door card.

My window has a similar prob, but its only in one position where it gets tight, and that's at the top. it's tight at about one cm from the fully closed position. (bit of an issue for making it water tight)

It makes a loud band and then goes up fully, taking the door card off is really easy, just a series of press-in clips and a few obvious screws.  But having removed it i still can't see the prob, perhaps i will have a look this weekend and take a few photo's for you to have a look at the general area behind the door card.

Thanks guys, will try that, will post the resolution on here.
