I Fixed My Window - You Can Too!!!!!!
I’ve only gone and cured it!!!!!
This is how I have fixed the sticky window on my 2.0 16v.
It will only really apply if your windows are sticky ie half inch at a time.
Remove all the door trims etc as you have previously done. Take care with the demister duct, and hold the mirror when you take the screws out – or it will fall straight off. Refit a screw to hold it.
Get the window to drop about 2 inches, it will make it easier in a minute.
Tape the window to prevent it dropping.
Feel behind the glass, you will find the clip that holds it to the rack. Fiddle the clip off. (This is shaped like the omega symbol on securicor vans, and has two lugs that clip in the spigot on the rack). Squeeze the spigot and withdraw it. This bit is bloody fiddly but do not be tempted to use a screwdriver or you may shatter the glass.
Undo all the 10mm nuts/bolts and withdraw the whole black frame. You will need to undo the membrane and insulation, this is also fiddly to replace so be careful.
Unplug all wiring and unbolt the rack from the frame.
Look at the motor. One end has a blue tube, prize out the brush springs from this end. Carefully prize the bent-over lugs that secure the end of the motor.
Now you can withdraw the end complete with that tube.
Look at the wiring – there is a very small thermal cut-out pushed into the housing – that is what caused me trouble.
Using a suitable length of twisted, bare wire, solder a bridge across the terminals on the cut-out.
It’s a good time now to clean the brushes, housing and commutator. Also you can lube the rack cleanly at this time.
Re-assemble and hold the end on while you test it.
Re-fit the end and bend the lugs back over.
In the best Haynes tradition, replace all items in reverse order!!
TIP: Be careful with the door release cable – you may have broken the small clip that secures it during removal. Secure with a cable tie.
Just remember though, in good order the assembly is quite powerful so mind your fingers – THERE IS NO LONGER ANY PROTECTION DURING CLOSURE. Be aware of this when raising the window as it will overload the circuit when it gets to the top.
DISCLAIMER. Obviously this worked for me, but I must accept no responsibility for any injury/breakages if you try this yourself.
