So hi! Guess I'll start by telling u I drive a 1994 K1500 W/T 4X4 with a 4.3 V6 Vortec. Ive been having problems with my brake lights working intermittently until now. They're gone - no brake lights. Instead, my seatbelt light comes on briefly when I hit​​​​ the brake pedal, and my blinkers act like they're on speed!!! I am so frustrated and baffled! Please help??
