1995 GMC Sonoma Hazard light switch

Electrical problem
1995 GMC Sonoma 6 cyl Four Wheel Drive Automatic

I need to replace the hazard light switch but can't manage to find out how to get at it the best way, I can remove the bottom cover of the steering wheel but there is still no axcess to the base of the switch. I can not manage to get the top cover of the steering wheel off, what should I do? The hazards are constantly onn and always draining the battery.
