cruise control has died

Actually it died a while back but I'm just now troubleshooting it. For the record, I have replaced every bulb in the truck with LEDs. The brake lights are Spyders with the LEDs built into the housing. I also replaced the flasher to remedy a case of hyper-flash when I changed out the brake lights. 3rd brakelight has a large epoxied box that I am assuming is a resistor. The brake lights do not have this item as best I remember, but I'd have to pull a light to confirm.

 

Fuse checks OK by meter. No obvious defects with either the brake switch (all lights come on and go off as they should) or the multi-function switch. With the truck running, in park and the cruise switch on, there is no voltage across the fuse. I don't think this is the speed sensor since the speedo works fine.

 

Where do I go from here?

My cruise control quit a few years back and while I didn't really use it that much I didn't miss it. Same thing happened on my 07' Suburban too.

 

Then the thought of it not working got to me. Read around and it seems that the solution was very easy.

 

Just had to replace the brake light switch located down on the brake pedal itself. Only trick is to push the clip up off the pin and it's a 2 minute job and the brake light switch cost like $14.00 but there are a few different versions of the switch for the different years.

I've seen that as well. It's either that or replace the multifunction switch, and the brake switch is a lot less expensive.

 

But before that, I'm going to check more on the resistors on the lights. That may be the issue.
