Ok guys I need some help, I'll describe whats going on. 2002 Silverado z71 extended cab. I got the truck wrecked and fixed it a few months ago. But last few days my abs and brake light on dash keep coming on and going off for a bit sometimes staying on. Sometimes they dont come on at all. But at times when accelerating it surges back n forth. I just installed a new fuel pump in it but the light thing did this before also just not as bad. Also sometimes the dash lights that arnt even on show up dim. And one time it said service 4x4 system, shut truck off refired it and was gone. One time also the right blinker blinked really fast like a blown bulb. Shut off truck and it stopped. I'm thinking a shorted wire or loose ground perhaps? But I wanted to ask what you guys thought.

 

Okay guys I am sort of leaning to maybe alternator is shot? When I am going straight if I use turn signal while accelerating it surges bad turn it off it goes away. Maybe that could be it? I'm heading to the auto parts store after work to have alternator tested so we shall see.

 

Okay guys alternator tested good. So bought new ignition switch. We shall see if that fixes it. i hope so

 

Bad grounding. Promise.

Put new switch in it and so far it's good to go

 

The problem has returned. I have another ignition assembly I'm going to try and see if it goes away again. But what's the likely hood in another bad switch
