This is a well documented problem, replace the turn signal/multifunction switch to correct this issue, this very problem happened on my GMC, it is a 99 as well, replaced the switch as instructed by a chevy forum member and it fixed the problem

I have had this same problem on two difference vehicles both of which are suburbans.

The solution is simple.
Remove the engine cover.
Locate a small ground wire that is bolted to the top rear of the engine block on the passenger side.
Remove the bolt, clean surfaces and replace.

This should solve your problem.

I know it seems too easy but it works.

It may be the switch on the brake pedal, it should be located on top of the brake pedal arn.

Disconnect electrical connector to brake switch brake located near brake pedal. Check for twelve volts or power with a test light on one side. If power, get a piece of wire, strip the ends and plug into each end of connector. If brake lights works, switch is bad. If not, check bulbs and power in the brake light socket. If no power, check to make sure power is leaving the trafficator switch as the brake light switch is depress or bypass. Check for broken or bad connection along circuit. If all good, you could have a trafficator switch problem. Oh, are the hazard and trafficators working in the rear? If they are, the trafficator switch is bad because the brake switch sends power there, then out to the back through the left and right rear trafficator wires.
