06 lbz heated seats and command start stopped working.

[Jeremyarti]

Hey everyone this is my first ever post here. I have a 2006 Chevy Silverado 2500hd lbz. It is a fully loaded lt3 and one day the heated seats and my aftermarket command start stopped working. I think they happened at the same time. Now when I click my heated seat buttons they just light up when I press them I hear a click then the light goes off. I’ve been checking the basic fuses and relays and everything seems fine. Anyone know what it could be?

One thing I think it can be related to is I installed led bulbs throughout the entire truck and I noticed when I did the interior ones if I clicked them on they would be dim but if I used the dial on the dash to adjust the brightness of the interior lights and turned it to the on position they would be fully bright. Now when I push them on before they would be dim now they don’t even turn on unless I use the dash dial. I’ve read before you sometimes need to splice in a resistor but for all I know it could be something else if anyone has any advice please let me know thanks in advance!

Welcome to the forum from Alaska. Do you have a scanner that can read the seat module? I am not sure about the 06, but earlier they were under the driver seat. I have seen so many problems caused by after market remote starts that I avoid them now.

Welcome to the forum from Oregon.

Yea, what @Cadillacmak said. I cringe every time I hear of the after effects of the led lights install and after market anything that may or may not last the warranty period. I am a stock kind of guy.

Swap the lights back and see if the issue goes away.

That's good that you paid attention to that and very well could be your issue.

Otherwise, you can do your typical check with a DVOM at the seat connector with the aid of a wiring diagram. Check Charm.li website.

And welcome to the forum BTW
