CHEVROLET SILVERADO CRUISE CONTROL PROBLEM

2009 Chevrolet Silverado • 51,000 miles

Sometimes cruise control works, a lot of times it doesn't. Brake fluid is fine. What could be wrong with the cruise control?

Check for applicable trouble codes. Some of the national brand autostores used to check codes for free. If you want to check codes, yourself, at the least, you need an obd2 code reader that will work with your year make and model. Check the wiring circuits for the cruise, when problem is ongoing.

I found this service bulletin. You'll have to decide if it applys. The fix is to reprogram the pcm. If you want a wiring diagram for the cruise, let me know.
