'20 Sierra Cruise Fuse

[C.Mc.]

I recently jumped my '20 GMC 1500 due to a dead battery and it took a few attempts before she turned over.  During the unsuccessful attempts the truck flashed and blinked and chirped all its lights and sounds.  Finally when I let it sit long enough connected to my other truck/jumper cables it worked!

 

But, I no longer can set or use my cruise control.  The dashboard indicates the cruise is activated but when I flick the thumb button to SET the speed, nothing happens.

 

What fuses should I check that are associated with the CC?  Or what else should I be looking for?

I'd try disconnecting the battery a few minutes and see if it resets. Did you have the battery checked or replaced after you got it running? These trucks absolutely hate low voltage and when jumping it off will throw a bunch of lights up like you experienced.

I second what 2016 Sierra Owner is saying.  GM has some DTCs that'll be temporarily saved, but not show a CEL on the dash.  These DTCs will prevent the cruise control from being functional until they clear out.  Pulling the negative cable off the battery for about 10 minutes could help.  Another option is to clear the codes with a scanner.

Thak you for the responses! 

(I'm an irrigation guy in Mass. so I've had NO DAYS OFF this fall and I finally got a chance to check this thread)

I'm going to try the battery disconnect today.
