I have a 2001 suburban LT. Used to, when you would press the lock button on the key fob the lights would blink once and if you pressed a second time the horn would sound and the lights blink again. Well just out of nowhere, the lights stopped blinking. When I unlock the blink twice like normal, but not when i lock. I really use the lights as a conformation because sometimes I'm in situations where i cannot sound the horn. Anyone have an idea? Is there some type of toggle for the lights? and also, is there a toggle for the horn? can i make the horn sound when i press the unlock also? and can i toggle the horn off completely? If anyone has any information it would be greatly appreciated! Thanks!

Do you have a DIC? All those type of options and more are found in the DIC options.



I don't think I have a better video of those exact options.

The option you're looking for is under "Remote Lock Feedback" and it'll give you the option for lights, no lights, lights with horn, etc.
