I purchased a 1999 yukon denali from my former brother n law; he didn't inform me that my windows, door locks, radio,and windshield wipers would stop working. I was told that I needed a body control module; one gmc mechanic asked me what does this part do. I'm a lady how would I know these things. I still don't have my vehicle repaired. Will this cause me other problems or can I continue to drive off a wing and a prayer?

While returning home from work today I approached a traffic light, pressed on the brake pedal and my foot went straight to the floor. I had to turn into the grass median to avoid hitting the cars in front as I pressed the emergency manual brake. Because I was very close to home at that point I was able to continue driving while using the emergency brake to stop. I checked the brake fluid level and it was within normal range.
Anti-lock braking system engages when coming to a stop causing vehicle to take longer than expected to come to a stop. I have had several near accidents including almost striking a pedestrian.
