Chevrolet Silverado 1500 2009 1500 V8 5.3L 265746 miles

Check out door switches. If one of them is failing the light keeps on.

4l60e transmission problem

Chevrolet Silverado 1500 2007 lt crewcab 4.8 214696 miles
Bought the truck used, it ran fine for bout a year then transmission starts acting strange. Wouldnt shift out of second gear, troublecode po967, low voltage shift solenoid b. I changed that still no imporovement. Changed ignition switch cuz everyone was saying it had a voltage drop at the switch, still didnt fix it. I found a bad ground wire so i fixed that, kind of improved but now the speedometer doesnt work sometimes and when it isnt working it wont shift out of second gear. But when it is working i have to shift manually for it to work correctly other wise when taking off from a stop it will start off in 3rd gear. Troublecode still only shows p0967. One other thing aotomatic door locks dont work

You can check the bulbs or if you lay under the bed of the truck on the driver side you will see a panel that is straight up and down with about 4-6 connecters on it i dont remember how many there are but anyways take off the connectors one by one and look at the piece you pulled off and if its got black or brown parts around the metal slits it is burnt and youll have to get a new one but check all of them.

I have running lights I have blinkers I have headlights but I have no bike locks that come on no press on the break
Catherine from United States 6 months ago
Same problem. Just changed the bulbs even though it would be unlikely they both burnt out at the same time. Still no brake lights. Will check the fuse when I get home. Did you get yours resolved?

Double-check all components underneath the distributor cap and ignition connector harness. Spark plug wires included. Now, do you have a signal or audio sound for the fuel pump while the key is in accessory mode? Does the fuel pressure rail consist of high-pressure or low-pressure flow?

Instrument gauges

Chevrolet Silverado 1500 2004 Crew cab/ 4.8l 154619 miles
All of my gauges quit working. Can only see the blinkers when on. Will show the battery symbol before starting. They have gone out before. Then while I was driving they all went to the right, like when you first start it, then started working again. I’ve changed 3 mini 10amp fuses under the hood associated when the cluster to no avail. Just a sushi chef trying to repair it myself and is frustrated at this point. Any advise or tips will be most appreciated thank you oh and it’s the extended cab not crew cab

So... I will no longer be towing my RV, so I began by pulling the fuse to my towing system which has connections to my battery & alternator. Once I pulled that 20amp fuse the battery did not die for 9 days! THEN, I left the truck sit for 2 days... & when I returned... IT NOW NEEDS A JUMP "ALMOST" every time I shut off!!
Im not paranoid... but I am a SWF traveling alone w. My dog & I've had a CPL creeps following me the last 2mo. It could be sabotage,
I had 3 more holes in my radiator & my back gas tank strap was missing. Oh! & my Mass Air Flow Sensor was unplugged. THATS when I realized this wasn't normal. Now IDK if I'm gonna find the cause of my repeated dead battery.

The reverse or back up lights, interior dome light and horn.

Chevrolet Silverado 1500 2005 Single cab V6 205000 miles
They do not work, it was my bro -n- laws, he passed away, so idk the cause only that they haven't worked since I got it, I've checked fuses, got new bulbs, checked the wiring, sockets and plugs. There is no dome light on the inside of the truck, I guess he removed it now could it be an incomplete circuit causing it,? Idk need some advise please??

The problem with your 2005 Chevrolet Silverado 1500 could be caused by a number of things. It could be a simple issue like a blown fuse or a more complex problem with the wiring or switch. To determine the cause of the problem, you'll need to do some further testing.
First, make sure the fuse is good. If the fuse is good, check the wiring for any obvious signs of damage such as fraying, corrosion, or loose connections. If you find any damaged wiring, it should be repaired or replaced. If the wiring appears to be in good condition, test the switch. If the switch is faulty, it will need to be replaced.

Electrical issues bad

Chevrolet Silverado 1500 2005  230000 miles
I have this issue. My cooling fans had gotten where they would stay running after I parked it and running my battery down . Then also my fuel pump stopped working and then started working again. But the fans come on when I turn the key off and turn off when I turn the key on. Now I have no power windows or locks only half of my instrument cluster works my abs and battery light and check engine all stay on . I have checked every fuse that I possibly know of I don't know what else to do?

Sorry in advance for the length of this. This truck has set for a couple of years the mice have found it home. I've not yet found chewed wires anywhere but there has to be some. I put a used battery but a good one in it and tried to start it nothing happened at all. I started looking into the fuses. I found several missing one of my boys must have needed some I guess. I don't know if I have found all that is missing and I'm not sure how to find out if ive got them all replaced. So I finally get some dash lights to come on battery light, brake light, and of course the lock down is also on. T… Read complete

Crank no start

Chevrolet Silverado 1500 1998 Silverado  228435 miles
1998 chevy Silverado. Have spark and strong crank. Battery good. Thought it might be security system but realized after going through that process that my security light was not flashing to begin with so I think I can rule that out. Would really appreciate some guidance on what to do from here. Thank you!

3rd break light wont shut off.

Chevrolet Silverado 1500 2011 5.3 175000 miles
I replaced the whole break light and the bulbs too. When I shut the door and then off all the light and lock the door the 3rd break light wont shut off it will stay on till battery dies. I was told to cut yellow wire but that didn't fix it either. What can I do to have a break light and lights when driving but need help them to shut off when I shut off the lights. Where do I locate the problem fuse box under the hood or I was told maybe a fuse or a plug in under the break pedal I have unplugged all of them but it still stays on.

I have excellent heat. But I cannot get it to move to the floor or to defrost. I installed a new heat actuator. It did not help. I have the manual controls. Is there a fuse that may be bad. I have seen fixes for the dual heat/ac controls.
