The bulbs in all the switches as well as dash lights tend to burn out, I mean you’re talking a 16 year old vehicle with over 200,000 miles. They’re all incandescent in this model year so no forever-lasting LED’s like the 07-up. I can tell you from experience they’re not easy to replace, at least not the ones in the switches. You can buy the bulbs themselves if you’re good at soldering tiny things or you can buy used switch modules with new bulbs, either incandescent or led. I bought bulbs from https://carradiobulbs.com/ and they have some good how-to videos. eBay has sellers that replace the bulbs and do exchange modules I think where you pay a core charge. Others will chime in I’m sure.
Apparently cannot read when you have 2 inputs to your bulb and 1 of them makes the bulb dim that means the switch has too much resistant take it out clean it out real well spray it was contact loop that's all what's all it's BS about diodes LED's.. LED for 12 volts are all ready to Use on 12v All aparts stores have them they put out more light and last much longer. You're also talking about 4..5 times more Cost
Well, I have a Bachelors, Masters and PhD in Electrical Engineering and about 50 years working with automobiles. Pretty sure I know what I am talking about.
Apparently it’s you who needs to learn a thing or 2 because you’re wrong. LED’s behave differently than incandescent bulbs and you can’t always just stick them in place of each other in an automotive circuit when there’s a computer monitoring and controlling them. I was an automotive electronics tech and I know this to be true. They have a polarity as well as almost no resistance where incandescents have no polarity and higher resistance. This can cause issues for the lighting circuits in vehicles.
nice, i have some auxito's I have had in for years now and they still work like new
not to feed the monster but your wrong in regards to these vehicles, the voltage on these vehicles is often based on the load "resistance" less resistance will create less draw and therefore less voltage which is why you will have issue's with led bulbs which have very little resistance inherently so "some" aftermarket companies got smart and started adding resistance to there led's so that they will have the proper resistance needed to make everything work properly.
Pretty close, it measures current draw but less current draw results in more voltage. It’s discussed in the basics of electronic theory in the equation known as ohms law which I’m sure everybody has heard of. What’s still fascinating to me is most of how electronic circuits work is still a theory with only a handful of actual “laws” that are known. Thus when you go to school on it, the classes are called things like “dc theory” or such. I have forgotten almost everything I learned but that was 40 years ago. I remember it was almost all trigonometry and math was never my favorite subject. Calculating voltage and current drops in complicated circuits combining parallel and series circuits and including all the different types of electronic components was ridiculously hard involving sometimes dozens of trig equations. I was known to use a somewhat shotgun approach to troubleshooting based on a few known factors because it was faster and thus I could produce more repairs in a day than the guys who would use the brainiac approach. Plus all those calculations would make my head hurt. This was a time when my brother was still alive and we worked side by side. Ahhh, thanks for letting me relive some golden memories.
I was spitballing it, lol I really don't know just going off of what I have seen happen on these trucks, the high speed lan bus is a screwy thing to me and the global b stuff even weirder when I hook up the gds2 to the silverado it gives me all kinds of communication errors, yet everything works....Pretty close, it measures current draw but less current draw results in more voltage.
