Suddenly my car is facing these 3 problems

[iamcs]

Hi all,

I am new here. My name is CS. My car is Ford Fiesta MK7 (ST). I've been driving this car for 3 or 4 years, and everything has been ok until yesterday. It just started suddenly, and would like to hear what you guys think about this:

1) the driver side power window cannot be roll up or down (but the rest of the 3 windows are fine)
2) when I lock the car, the side mirrors do not fold in (locking using remote control) - yes the "Link to Lock" is enabled
3) i cannot fold in/out the mirrors nor adjust them manually as well - the manual fold button is not functioning

Changed the fused, but it didn't solve the problem. Now, the only assumption is that the power window button of the driver's window is broken. But how does this broken button affect the side mirrors manual fold button? Anyone has got this problem before? Please do share your opinions.

Many thanks!
