Cruise control intermittent

Module going bad?

Cruise control intermittent

Postby AnbroBR [OP] » Sep 18 2020, 12:12am

The cruise control on my 1995 GMC K2500 seems to not want to work sometimes. I can set the cruise control and while driving down the road, it will sometimes shut off. None of the indicators (brake light; ABS light) light up or even flash when this happens. The cruise control just shuts off. I understand that the GM part number for a new cruise control module is 25315088 but they are no longer available from GM. Thanks for any help!

Before you do that check the integrity of the wiring from the cruise control switches/ buttons down the steering column. Make sure your brake switch is operating properly.

Thank you; I will check those things out. I have noticed in the past that when I use the emergency brake, I sometimes have to move the lever by hand (or foot) to its fully raised position. The brake warning light alerted me to this. I do not know how "sensitive" the brake lights switch is on the brake pedal. I probably ought to check that out, too.

The last time that I got into the truck, I did a little checking. I found that I had to press the brake pedal down at least 1/4" before the gear shift release solenoid would energize. So I am assuming that this is the point at which the brake lights come on. I didn't have anyone handy to look at the brake lights for me, but this is what I have found so far.

I drove into town the other day and the cruise control would just quit. I would turn it back on and it would work for awhile and then quit again. Later the cruise control would not work at all. It appears that I am "up a creek without a paddle."

289,025 miles on the truck now...

An easy way to check your brake lights is to either back up close to a wall or garage door and you can see pretty easily at night. Or you could back up close to a store or some place that has a big glass window so that you can see the lights in the reflection off the glass.

My 2008 Silverado did the same thing. Brake lights worked fine, but it was the brake light switch. Changed the switch, now the cruise works fine
