i need window fixed for inspection soon-wont stay up off track or something. Man told me regulator 150 bucks but WHOLE door in junk yard off a car with manual windows much cheaper than that.Would this mess up other electric windows? I dont care about electric mirrors but door does have switches for all other windows on it as well as those doors?. Also paint is crappy dont care about mismatch. Not very mechanical any help greatly appreciated!!!!!!
