Power Mirror Control

I have a 96 K-1500 and the L/R mirror control knob broke off, does anyone know if I have to replace the whole control assembly?

Thanks

Sorry to say but you do. they arent that expensive when you order them from the internet, but directly from a GM dealer theyre bout 70$

Thanks for the reply, I had to fork over $61.29 plus tax at the dealer ship, but I am glad it is back to origional, those little light bulbs are really distracting shining up in your face at night!
