Top 20 2006 Chevrolet Silverado Questions & Answers

There are some ideas in the link, but because of the Cruise Control issue, I think you need an auto electrician as things like this are controlled by ECM and BCM. https://www.google.com/search?q=2006+chevy+silverado+brake+lights+not+working https://www.google.com/search?q=auto+electrician+near+me ..

Is the security light lit in the instrument cluster ? Anti-theft will disable fuel injectors after a second or two if anti-theft has a problem .

Before you start replacing parts ,need a little more information . Maybe able to save you some time an money . Does the horn work when you push the horn button , does the air bag light stay lit in the instrument cluster ? The button lights for the bottons on the steering wheel are lit by the BCM - body control module . Interior Lamps Dimming The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps. When the ignition switch is turned to the RUN position, the radio's vacuum fluorescent (VF) displays turn on at maximum brightness. When the park lamps are on, all incandescent back lighting turn on at the dimming level indicated by the I/P dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the BCM. When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch. The following switches and components have back lighting when the park lamps are on: • The instrument panel cluster (IPC) • Radio, front and rear • Window and heated seat switches • Garage door opener switch • Selectable ride switch • Roof beacon switch • Power take off (PTO) switch • Headlamp leveling switch • Rear wheel steering mode select switch • HVAC control assembly • Headlamp and panel dimmer switch • Transfer case shift control switch • PSIR disable switch • PRNDL lamps • Traction control switch • Steering wheel control switches • Fog lamp switches Could be the clock spring inside the steering coulmn ,under the steering wheel if horn doesn't work ,air bag light lit etc...

It sounds like the grounding is not good.

Check all the earths in the circuit especially the one from the engine to the chassis and make sure they are clean and tight.

What about battery? Recharge or replace battery, try if it cranks. If not, write me or find a mechanic. If yes, check voltage with engine running - it should be about 13+ Volts. In the opposite case, check the alternator.

The daytime running lights should not flash when locking/unlocking the vehicle. It should be the park lights that flash. You may have changed the wrong bulbs. These lights operate from a sensor located in the center of the dash and use the suns ultra violet rays to go from daytime lights to headlights. Make sure this sensor is not obstructed/covered by anything that may be on top of the dash.
