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.

      No Software Updates - Old Build

      By Atlas · Posted

      In addition to a cell or wifi connection, the infotainment needs to be enabled to download software updates. That's a toggle within the system settings.   But...if the truck was prevented from receiving updates in a past life, missing a bunch of updates may mean it won't go back and download all of those because they're not available or the system is too far out of date.   If a formal recall depends on a software update, the recall for that truck remains in an open status until it's applied. The dealer would need to apply the software update in that instance.   Most updates downloaded and applied via the infotainment aren't recalls/safety recalls, they're enhancements and usability fixes which aren't critical.

      Brake Pad Warning Message

      By Vu1can · Posted

      Recently I've been getting a message, "New Brake Pads Detected. Reset Brake Pad Life?", But I haven't had the pads replaced and the truck only has 28,000 miles. The Brake Pad Life shows Front 64% and Rear 79%. I select NO to resetting the brake pad life and the message goes away but comes back at the nest restart.   I stopped by the dealer and was told that it sounds like a software glitch that would require reprogramming. Even though I have the extended warranty, they tell me that reprogramming is not covered unless a module was actually bad and needed to be replaced. Simply reprogramming is not covered. So, they want $200.00 just to diagnose the problem. If it turns out no bad module, another charge on top of that to do the reprogramming. If the cause was an actual bad module, everything would be covered under the warranty.   Just wondering if anyone else has had this problem. Should this issue be covered under the warranty?   Thanks

      NHT is diesel only, correct.     The GVWRs for NHT on 3/4 ton bring them to the same numbers as many of the 2WD 1 tons.  A crew 4x4 standard 3/4 with NHT is 11,750lbs, a 1 ton same cab/box/4x4 is 12,100lbs.     Hubs and hub bearings are the same for 11.5" and 12" axles.  Housing, diff carrier and ring/pinion are larger for the 12".   All gas use the 11.5" axle, 3/4, 1 ton and 1 ton DRW.

      For most of you, this is probably outside your realm of interest, but, maybe you can appreciate it. The hood and wheels aren't something I'm interested in, but someone made a very rowdy Audi S4... amazing sound.       These were/are very fun cars for the money.   Not going to lie, I'm getting an itch to own a newer Audi RS3. The 5-cylinder will be changing, or going away, at the end of this year.
