How do you replace the turn signal switch...?

How do you replace the turn signal switch in the steering column? I have a buddy that needs to replace his on a '98 GMC. He has no turn signals, or brake lights.

very carefully

The Turn Signal switch, hazards, etc. should all be one assembly.
Remove the two shrouds around the column
Unplug the various harnesses for the "multifunction switch" as they call it.
remove the screws holding it to the column
plug in and test the new one
replace the whole assembly
replace the shrouds
drive on

you may have to pull the steering wheel to get to all the screws.

If he has no brake lights too.......he may have an issue in the column itself.
