Genuine or non genuine power window motors?

[trentopatrol]

Hey guys I bought a cheap kit off ebay for power window set up for my 89 gq but they dont seem powerful enough to lift the windows. The car never had power windows so before I spend a buttload of money on genuine motors was seeing if they are actually worth the hassle. What do you guys reckon?
Cheers

Maybe start with renewing your window frame rubbers and lubing up anything inside that helps wind it up and down

I have original power windows in my 92 GQ and they struggled lifting the windows last time it was on the road, although the motors are old and could possibly be on the way out also

Thanks mate, ive tried lubing up the rubbers and installed new actuators, even tried pulling out all the rubber so there is 0 friction and it helps but still doesnt quite do the job with the motors i have :/ might just have to bite the bullet and get the motors
