And the horn stopped working
A few weeks ago I replaced the dimmer/horn fuse because it had popped...the fuse is still intact...

Sorry I don't know how to start a new thread

Check all the fuses, goofy stuff happens when one blows. Do you ever use the cig lighter? That's what always takes out my fuses.

To start a new thread, just pick the appropriate category and click on the "new thread" button.

That's what did it the first time
So I pulled the cig lighter and put it in the glove box.

I'll check the fuses when I get off work.
Hopefully the truck starts.

Damn, that's a nice Burb. Welcome to GMSB. You need to get you a build thread fired up in the Under Construction section so we can get those gremlins worked out of it.

When I have some free time I will
I have a 2yr old and my wife is days away from #2
So for right now as long as she gets me to work I'm good

But the list of little things that need addressing keeps growing!!!
Not to mention trying to find a 12v Cummins and an NV5600...

I went through the fuses and they are all good
But when I pulled the "TL CTSY" fuse the light turned off
Also the horn relay isn't making noise anymore

Any thoughts?

Thr TL CTSY circuit I do believe is your dash lights, tail lights and interior dome lights. You pretty much need that circuit for night driving. I know this when trailer wire shorted out once and I lost tail lights, dash lights and dome light. Made for a rough trip home and I did get pulled over by LEO due to no lights.

Guess I'll be doing some wire checking this weekend.
For now I pulled the bulb.
Thanks

You can download those pics to your iPhone so you can look at them while in the truck, or print them out of course.
