Lighting, Turn Signal Issues w/ 2002 Avalanche
Rather than snagging someone else's thread, here is my situation.
I noticed a while ago that water had gotten into the passenger fog lamp. But the lights still worked, strangely enough. A number of months later, my driver side fog lamp went out. I replaced the bulb, noticing that the socket has become brittle and burnt. I read somewhere that the older sockets needed replacing, so I have those on order to replace, including the whole assembly.
Then, my driver side headlamps (low beam) went out, within a week or so. I replaced that bulb and things were good, except I broke the tab off of the turn signal assembly. Didn't think much of it until I noticed the turn signal bulb and mini side turn signal bulb on the same side burnt out at the same time. I guessed it was because of the little bit of play in the assembly, water had possibly gotten into the engine area. So I replaced those two bulbs, then rigged the assembly to stay in place.
This morning however on that same site, the left signal was doing the fast blink repeat issue. I noticed with the dome override on, and turn signal on, the main turn signal bulb was not blinking. Once I got on the road, the quick blinking stopped.
It's feeling like I have some more major electrical issues going on. Every time you get out of the truck there is ESD. Feels like maybe a grounding issue, but how does one fix that? Also I read somewhere possibly fuses are looking to go. Any reason I shouldn't just replace every fuse in the box?
Are there any common issues w/ the first year Avalanche like this?
