front power windows not going down properly

[Jezza]

so i was just using the front windows as normal and after i had gone and done something i got back in the car to go and the front windows only go down in very short bursts so to get it all the way down i have to keep pressing the button till it gets there but the windows go up no problem and the back windows arent effected and i have checked the switch by testing it in another vy and it worked fine

im stuck for ideas and was wondering if anyone knows what could cause this

might be the regulator on the window jezza

Try Cleaning the Door Window Seals where the window glides up and down against. Clean it and then spray some silicone spray around the seals. I found this helps heaps when my windows starts to get slow to go up and down. The Window flys up and down after. But it could also be the regulator. May have to lubricate the mechanism inside the door window. Might be some binding.
