The Chevy Silverado is a workhouse of a pickup truck. The HD and HD models are made for towing heavy loads. The Chevy Silverado is the more passenger friendly version that benefited from a redesign in Luckily, hw97 fac electrical systems of all Silverados hit more than they miss. Still, it pays to know where to look if you do experience electrical problems.
Expect the more common electrical system problem to affect the lights. When interior lights start flickering or just don't want to work at all, your first step is to check fuses and relays. If that checks out, look for a loose wire connector. Don't forget to check the ignition switch too. Examine the ground cable from the engine to the firewall, particularly if you're experiencing more than one electrical problem. Connections particularly come loose around the firewall. Check your wiring if you flip a turn signal and instead get emergency flashers coming on.
This happens sometimes when trailer wiring has been added, causing electrical system problems. Consider having the BCM or Body Control Module replaced if your Silverado repeatedly blows out the same fuses or if it seems like you're experiencing one electrical problem after another.
This job must be done at the dealer so that they can flash the computer after replacement. Contact GM if a relatively new Silverado starts acting up. It could be that there is a TSB technical service bulletin or recall that addresses the problem. If so, give your dealer the TSB number and expect to get your repair made for free.

The battery in my Chevy Silverado died yesterday and before that it would start and run fine. Now the problem is I charged the battery and tried to start it it will turn over like normal and start for about a second and die. Now the question I have is does the passlock system need to relearn the codes again before it will start?
5 Common Ignition Switch Problems and How to Fix Them
And will the battery going dead cause the problem? Do you. If you are getting any kind of security system indicator, here is the relearn procedure.
Disconnect the battery and hold the cables together for about 30 seconds then reconnect the cables before performing the procedure. Read it carefully if done incorrectly it won't work. If it helps let me know. Attempt to start the engine, then release the key to ON vehicle will not start. Turn OFF the ignition, and wait 5 seconds. You must turn the ignition OFF before attempting to start the vehicle.
Was this answer. Is the security light staying on? Let me know. My used Silverado has the anti theft feature and I don't know the unlock codes. After the battery was changed my radio no longer works. How can I obtain the security unlock code? Or do I have to take to dealer?
You will need to see a dealer to get that bypassed.My ignition switch does not always work I know it is in the stearing colum somewhere but just cant locate.
If i keep turning the key cylender on and off it wil eventually kick in I know it needs to be replaced but dont know where it is.
DavidH25 answered 6 years ago. The hole you put the key in. If i keep turning the key cylender on and off it wil eventually kick in I know it needs to Disconnected the battery for over 30 minutes and for one day the engine light did not come on.
Can someone help. Stays in 2 wheel drive. I have a different car. Content submitted by Users is not endorsed by CarGurus, does not express the opinions of CarGurus, and should not be considered reviewed, screened, or approved by CarGurus.

The mechanic thought this was most likely just due to age". Servo is the problem yet to be changed". Has been changed twice. Works ok for about a year, then starts acting up again. Expensive repair". Living in Texas, this is a critical fix". Stopped working on high speed". Had to replace blower motor resistor". The hot air still comes out. You must pull off the road immediately and turn off the vehicle for a few minutes to allow the system to reset.
If you do not, smoke comes out of the dash and the wires melt together.
How to Troubleshoot the Electrical System in a Chevy Silverado
Happened to us 4 times". Have to replace periodically". Paint fading, chalking, cracking, or peelingloose interior and exterior trim or moldings, rust. GM should be responsible.

There are many problems that can result in a Chevy Silverado's failure to start, making diagnosing the trouble even more frustrating. Depending upon how the failure occurs, you can check for several basic problems before making the decision to call a mechanic for assistance.
Not turning over is usually a result of the starting system failing to get the required electrical power needed to turn the starter. When you turn the key and get no result at all from the engine, it is commonly due to bad battery connections or a discharged battery. Less common problems are a break in the starter circuit's wiring, a faulty starter or a faulty solenoid. Before suspecting electrical or mechanical failures, however, ensure that the parking lever is in park and that electrical connections are clean and secure.
If the engine turns over but will not start, this usually means that either the engine is not producing a spark at the sparkplugs or fuel is not being delivered to the engine. Common causes for no spark are a weak battery, indicated by a slow-turning starter, a faulty ignition coil or a wet ignition system.
Less common problems are faulty sparkplugs, broken or disconnected coil wires or broken wires in the ignition system. A fuel delivery problem is usually caused by a clogged fuel filter, no fuel in the tank or a faulty fuel pump. A starter that spins without turning the engine is caused by the starter gear failing to engage the engine's flywheel.
This usually indicates that the starter pinion is sticking and not allowing its gear to move into position with the flywheel. Less common are broken starter gears or broken gear teeth on the flywheel resulting in the starter being unable to contact the flywheel. An engine that's hard to start when it is cold is caused by the engine either producing a weak spark or not providing enough fuel to the cylinders.
A weak battery will produce a weak spark at the plugs, and will turn the engine over slowly. A worn distributor cap, old or broken plug wires or a worn distributor rotor can result in a weak spark at the sparkplugs, causing the engine to turn over excessively before catching. A clogged fuel filter, dirty fuel injectors or weak fuel pump can result in too little fuel reaching the cylinder, causing poor fuel ignition and the need to depress the accelerator to assist starting.
An engine that is difficult to start when hot can be caused by a clogged air filter restricting airflow to the intake. This causes a rich condition at hot startup, often noticed by "flooding," or the smell of gasoline after repeated starting attempts. Another possible cause is a weak coil or electrical system that is compounded by the heat produced from a hot engine. Heat increases resistance in electrical systems, lowering the effective voltage at the critical ignition components.
Less common problems include faulty emissions systems that must be diagnosed by checking for fault codes stored in the vehicle's computer with a scanning tool.
