2008 c300 window

ive been dealing with an issue with my 2008 c300 for some time ...
soooo i changed the master switch on my drivers side for the window because the button had broke.
the shop i went to told me that would work and in fact it did when they first installed it .. the first day the windows were working well when i would push the button it to go down
but the following day when i turned on the car.. there seemed to be no power going to the master switch .. the reason i figured that was because the master switch has two orange indicators for the side mirrors and those were no
longer luminated .. soooo i thought of checking the other windows and now none but the passengers side is going up and down .. before the master switch was changed the other windows were going down ...
ive searched and searched online to try and avoid having to pay an arm and a leg to find the solution ... Does anyone have any idea what it can be ...
(i ran into some forum a while ago which cant find again that told me to remove a fuse from the fuse box under the hood and turn the car on ., i did it and it worked that day but when i shut it off for the night and turned it on in the morning same problem once again )
