Hey guys, when I turn my blinker both blinkers flash the selected blinker flashes brighter (Does this for both left and right selections). Horn doesnt work unless key is out of the ignition when I press the horn both blinker dimly light up on dash, same with turning on bights and fog lights. Air bag light is on also.

So far I redid the Left side frame grounds, made sure the engine to fire wall ground is good. Can any modules cause this? I plan to check other grounds also I just found a diagram for a 02 which I assume should be the same.

The truck came from the north so its rusty. Honestly was a bad buy didnt notice how bad the rust was until I purchased it, but it was intended to be a work truck so its all good.

The truck is a 2005 Avalanche Z95 4x4

 

I assume you got this resolved, I just installed a new blinker/multifunction switch with help from Youtube, cost about $30 and took about 30 minutes. Let me know if you didn't get it figured out.
