GM Genuine Parts D1586H Brake Light Switch

Solved cruise control issue.Mounted in as replacement just fine.

Let me guess, you're looking for this because your GMT900's cruise control is funky? If the light on the steering wheel button illuminates, but your CC is intermittent/nonfunctional with no other warning lights/error messages, it's almost definitely this switch.Install took exactly 5 minutes, not including the time in took to contort myself halfway upside-down to reach it, but you're one 10mm bolt and a retention clip away from swapping it out and regaining full functionality. There's cheaper third-party options on here, but for sub-$25 dollars for a genuine OE replacement, why gamble for a few bucks? Worth the price to trust it the first time, in this case.

Worked perfect restored my cruise control.

My cruise control was not working periodically. Sometimes I would drive and it would turn on just fine, other times I would press on the button and nothing.To validate that the Stoplight Switch was the problem, I was driving and the cruise control would not turn on. I pulled up on the brake with my foot and then tried the cruise control. It seemed to work fine. Duplicated this a couple of times and so I went ahead and order a new switch.Installation was a pain. The bolt was easy enough to remove. The problem was the clip was difficult to remove. Putting on the new switch and then trying to get the clip back on, was again even more difficult to get it to snap back on to place. It eventually snapped back on and I then screwed back on the bolt. Do not over tighten the bolt.After everything was put back together, the cruise control is working and I have not had any issues.This switch tends to go bad frequently. In the past I have had the mechanic replace it. If your cruise control works sometimes, you might try checking the stoplight switch.

If your cruise control stops working or your brake lights are always on, this is what you need to fix that. It usually means the switch is not disengaging all the way. Super easy to install. Buy the gm one if you have power adjustable peddles otherwise your abs will not work.

Anything you have to work on upside down, in the dark and on your back, challenges. This is no exception and even adds a difficulty factor due to a retaining clip from hell-o. Not these guys fault, the part is spot on and repaired my flaky cruise control issue that has plagued me for months. It's a GM thing, if your reading this you know what I'm alluding to cause you've been there. If not you're about to, this clip is nearly as frustrating as trying to re-hang the covers after an HVAC blower change. Spoiler alert... pry the middle section out and push up towards the roof. Good buy.

Great product. Good as factory part. Fixed my cruise control problem.

I was extremely pleased with the brake switch and worked just as it should have in the first place. I own a 2008 Chevrolet Silverado 1500 LT and noticed when i tried turning the cruise control on it would not work. My brake lights worked but the cruise control did not work. I learned this by pushing the cruise control button on the left hand side of the steering wheel and then hitting the set button which is underneath the cruise control button. There should be a light on the gauge cluster when you hit "set" that looks like this: https://upload.wikimedia.org/wikipedia/commons/thumb/1/15/Cruise_Control.svg/2000px-Cruise_Control.svg.png . If that light comes up on the gauge cluster then your cruise control works if this light does not come on after hitting set then your cruise control is not working properly and it is likely that you have a faulty brake switch. For my application, when I hit set nothing would happen. I did some research and figured out this was likely the issue. For 13 dollars I realized it's worth a shot. Today I got the part which was in a small plastic ACDelco bag in a medium sized packaging envelope. Things you need are a ratcheting 10 mm wrench, a flash light, and a flathead screw driver. I followed this video and was able to get the job done https://www.youtube.com/watch?v=pHwWV98wBZU&list=FLlh_SarivhBqFnENckkrktA&index=3. The hardest part about this entire install was the retaining clip. As long as you stick with it you can get that clip off. After about 20 minutes of work I was able to complete the job and take the truck for a test drive. Beware: You do have to go over 25mph to use the cruise control. The cruise control finally worked and I had a huge grin on my face the whole way home! I highly recommend trying this if your cruise control does not work.
