Q: Window Malfuntion on 2002 BMW 325i

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have a 02'Bmw 325i, I brought it used & when I got it the windows didnt come down.... I thought it might be my fuses so I changed them all, still didnt work so maybe a possiblity its my radio wiring right? I took that out & it still didnt work! I dont think all my window motors are blown because neither does my sunroof work.... Any solutions or suggestions?

I replaced all my power windows about 3 or 4 times already. Dont buy a regular replacement parts from BMW it is very expensive, buy it from it like from Auto zone or Kragen. the have a life time warranty. BMW window regulators brake down easily. It is easy to replace this regulators. Or at least if you want to keep your 325i learn how to replace it.
