Cruise Control Issues

cobrajet84 · August 27, 2013

Alright, my cruise control is being intermittent on working and not working. It'll work for a while and then not work and will occasionally kick off on its own. Checked the fuse and it is good. Did a search on here and that led me to the brake light switch, but I have purchased the brake light switch and replaced it twice actually. Both times I put the new switch in and it makes the problem worse. It actually causes my brake lights to stay on which is not happening with the original switch. Any ideas or is it really possible that I have gotten two bad replacement switches? It's a 2007 GMT 900, 5.3L LTZ.

Where are you buying the switch and are they giving you the right one ?

Buying it from oriellys...it's the one that comes up when I search online and looks exactly the same as the one I take out

Do you have the adjustable pedals? I would double check with a GM dealer for a part number just to be sure. You might be chasing a ghost.

I do have the adjustable pedals, and the guy at the last oreillys I got the part from brought the one out that was supposed to go with the adjustable pedals, but it was completely different from the one that is in my truck.

Thats the reason I mentioned that you go to a Gm dealer with your VIN #. That way you know what the right part number is.

Alright, we to the local dealer, only one part number came up. So this is a case of rand does matter. Got an ACdelco brand one from the dealership and the cruise seems to be working great. Swapped the part out in the parking lot just to make sure, lol. The two BWD branded ones from oreilly's didn't work. So if you have to swap out your brake light switch go with the AC delco version.

Well I am glad to hear you got it fixed. Some times you will chase yourself into a corner and spend All kinds of $$$ just because the part you bought was junk and didn't work. I have done the same thing and learned the hard way. So when I can I always buy OEM. It might cost a little more but in the long run it is usually cheaper.

As far as I know GM did some improvements on the switch.

Maybe that's the reason why the one you've bought at the dealership works and the others not.

That's what I figured in the end, luckily returned the non working ones easily and the part was actually cheaper from the dealership anyway. Just glad the truck is working, was begging to think it might be something else.

Hmmmmm you are making me worried now. I just ordered an O.E. PRO brand turn signal/cruise control switch for the pontiac listed in my sig because my cruise control stopped working all together. I checked the fuses and relay and they are all fine. The part I ordered from rockauto was less than half the price of the AC Delco part and I really dont want to spend too much.

Hopefully the part works like it should. There is only one way to find out I guess....

Just a follow up to my last post, The O.E. PRO brand combination blinker switch I ordered from rockauto.com fit and worked great! The cruise control is back and working like it should. The headlight switch is a little stiff but I am sure it will break in over time. I am happy.
