Ok so hopefully someone on here can help I've got. 98 blazer 2 dr and something going on with the electrical system I just replace the motor so I might have messed something up there. The top turn signal in the front head light went out so I changed it blinker was blinking fast now it kinda works but still blinks fast but the other side is brighter than this side so could it be a ground? Also sometimes I can turn my headlights on and off and sometimes they stay on no matter what. Also when I hit the brake the third brake light comes on for just a second then goes out?

Any help??.?.
