lamp lens / window mechanism.
I am having some difficulty with the drivers door window on my Alfa 166. The drive motor starts to labour when the window is about half way down, sometimes even cutting out if the strain gets too much. After this, it seems to free itself up again, and continues to the top/bottom position where it stops correctly. I have had the door panel off and cleaned the window slides, subsequently lubricating them with silicone spray. I have also applied grease to the quadrant gear, and dry graphite spray to the horizontal slides. All this has made no difference to the performance of the window function. Has anyone got any tips or experience in this matter, before i proceed to strip the whole mechanism out to investigate?
Can anyone advise me where I might be able to obtain a o/s/f headlamp unit (motorised xenon type) at a sensible price, either new or second hand? The bulb and the operation of the lamp is fine, it is just that I had a stone smash the glass!
