Electric Mirrors not working? Help?

Hi,

After browsing the forums for a few months, the time has come for my first post; before I start I should say I have looked everywhere for a solution to my problem.

When I locked my car and held the button to fold the mirror, the passenger side mirror did not fold. I unlocked the car and tried again; both worked as normal.

Since then, my car had been sat for a while in cold, icy conditions. When I came to use it, the mirrors folded down as normal upon unlocking. I later reversed my car when parking and the passenger mirror dipped to the kerb, as normal. It would not fold up though!

Since this, my electric mirrors do not work at all; no power fold, no adjust, no dip on reverse. I have tried to adjust them several times with no success.

What could be the problem?

Thanks in advance for any help!
