Programmed keyless remotes and now horn won't work...

[redbugdave]

I have an 06 GMC K2500 SLE. I needed to program a new clicker and went thru the normal directions:

 

1. Close doors.

2. Insert key, do not turn.

3. Press and hold door lock switch in the unlock position ( on the door).

4. Switch ignition on, off, on, off (or on, lock, on, lock) Note on does not mean Start.

5. Release door lock switch.

6. Doors should lock and unlock one time to confirm programming mode.

7. Simultaneously press and hold the LOCK and UNLOCK buttons of the first remote transmitter for 15 seconds.

8. Doors should lock and unlock to confirm programming of the first remote transmitter.

9. Repeat steps 7 and 8 for all remaining transmitters.

10. Switch ingnition ON to exit programming mode.

 

It worked, and I got my clickers all programmed OK.

 

However, I noticed my horn will not work when manually pressing the horn on the steering wheel. The horn works by using the horn button on the clickers, though. I disconnected the battery, hoping it would reset something, but that did not help. My truck does not have the DIC. It did something when I programmed the clickers.

 

Any ideas on how to fix the horn function?

Are you 100% sure your horn button was working before the programming? Mine could be out for months and I would never know it.

Hi Waumo1...

 

Yes. I used it the previous day. I feel it has to be in the programming after doing the clickers. I just want to figure out how/what I did to disable the horn. The programming went fine with the clickers.
