Cruise control on 06 Sierra
Does the horn honk? if not check the fuses, if you find one blown then you need to run a circuit check to find the offending unit or wiring.
Cruise works now. It appears to be an intermittent issue. Yes my horn works too. But the other day my keyless entry quit and and now it works. Could these two be related?
Start checking the main power distribution connections, make sure none of them show burning.
Already did. Everything looks as it should. I'm thinking it may be a control module
BCM failures usually stop all of the accessories not just a few, but today anything is possible, possibly the dealer can reflash the system.
