No Brake Lights and Brake Controller not working

I have a 2000 GMC Sierra 1ton 4x4.
The brake lights are not working, only the 3rd light on the cab is working when applying the brakes. Tail & turn are working. The brake controller is not.

My other 1/2 says there is juice to everywhere but the multi function switch (turn/wiper/cruise); expensive piece to replace.

I have read else where it could be a bad Brake Light Switch; cheaper to replace.

Anyone here ever had this problem?

Mine was doing the same thing yesterday. Over cab light worked but both rear brake lights not working. Checked the fuse even though the over cab light worked and it was OK. Pulled the top rear bulbs and put a meter to them. One filament in each bulb was open. Bought new bulbs and everything was good.
