My last post was about some topics I wanted to go more in depth about in the near future. First things first, a little auto repair.
The blinker in my truck stopped, well, blinking. The hazard lights still worked, so I can only conclude their was something wrong with the switch for the blinkers. I referred to my incredibly useful, yet monstrous, 65MB PDF that tells me all I would ever want to know about my truck. I learned that all of the blinker, hazard, lights, and wipers are all a part of this nifty little multi-function switch. Of course the PDF goes into how to remove it and put a new one back in place, but nothing about the inner workings of the switch. Before I drop $80 on a whole new switch I thought I'd just crack it open and see what makes it tick.
I would appear I was 100% right. Something was wrong with the switch and it was corrosion. South Texas' salt air, humidity, and heat can really wear things out around here. I learned long ago from my Dad you can clean corroded contacts with a pencil eraser, but never put that to the test until this. Now I know it requires a pencil eraser and a little bit of elbow grease.
Unfortunately, no amount of elbow grease seemed to make it work right again. Either I can't clean it well enough, or it's something more than corroded contacts. I'll probably end up purchasing a new multi-function switch.
EDIT: I was 100% wrong. Although the multi-function switch looked corroded, the multimeter test says it's good. I guess I'll go back to my PDF and try to find the cause my my blinker problem. I don't know what it is, but I suspect the little blue box behind the fuse panel that clicks when the blinker is on.
