Ecm relay making a clicking sound SolvedSolved

Chevrolet Silverado 1500 2014 Chevy Silverado 1500 5.3 135836 miles
Just finished rebuilding the engine and after installing the engine and trying to start the truck the Ecm relay starter a clicking sound and the Truck won’t start but as soon as I move the wire under the fuse box the car turns on. The wire is under the ecm relay. I’m not sure if the wire is broken or did I miss something while installing the motor. If anyone else had this problem before please let me know thanks 🙏

Ticking noise SolvedSolved

Chevrolet Silverado 1500 2014 PU 131200 miles
There is an annoying ticking that sounds like it's under the truck, maybe the exhaust. Had the valves and lifters checked and it isn't them. Has done this ever since ai acquired it at 126000 miles and hasn't gotten any worse
Anyone else dealt with this?

Hvac noise in cab

Chevrolet Silverado 1500 2007  140000 miles
I have been hearing a weird noise coming from the dash area. I took it to the dealer and they could not hear it. It is not very loud. If I turn on the air or radio it drowns it out. Once I reach 5 miles and hour the road noise drowns it out. It has been going on for about a month and it does not seem to be getting worse. I planning a 2000 mile trip soon and I want to make sure this nothing serious. I have a video file that I will try to upload here and I plan on visiting the dealership tomorrow. Any suggestions? Fire away.

On light throttle, makes this noise…

Chevrolet Silverado 1500 2015 4x4 177000 miles
Makes a noise almost like when you’re on the highway, and getting out to the side. It has those things that wake you up if you falling sleep, and vibrates. Just like if you run over those rumble strips, but it feels like it’s coming from my rear tires.

Low rhythmic sounds coming from rear of truck at high speeds only

Chevrolet Silverado 1500 2003 V8 5.3 fleet truck 8ft bed 131000 miles
The sound is a low rhythmic thump/"limp"/roar that matches the speed Im going but it only starts when Im going 75mph or more and once it starts happening, when I push pretty hard on the breaks, I feel it hard under my foot and the sound gets so loud when I break and I feel it so hard it seems like the back end of my truck is gonna fall apart. I love my truck, it only has 131,000 miles. Theres so much life left but I dont want to put anymore money in it if I cant figure out what this sound is. I have been told that it might be a rear differential problem but when I took it in to a specialty… Read complete

Chevrolet Silverado 1500 2008 5.3 flex fuel  2000000 miles
It acts like you don’t wanna shift or it doesn’t have the power to allow the car to even go above 45 miles an hour idles fine. It sounds fine until you try to accelerate change the throttle positioning center.

Throwing codes and cutting out.

Chevrolet Silverado 1500 2003 Z71 4x4 LS Ext cab 5.3 LM7 3rd Generation 191674 miles
Puts out all different kinds of codes one day and nothing the next day. 327 and 332 stay on because I have to replace the knock sensors. Again! New problem. Starred cutting out while driving, like it's running out of gas.

Noisy alternator

Chevrolet Silverado 1500 2001  260000 miles
My alternator worked great until it didn't. It gradually made a noise that sounded like a power steering pump that was empty. And it. Was putting out just over 12V. So I decided to replace it. A trip to O'Reilly's for a refurbished one. I swap it out and it's louder than the old one. But it's putting out around 16V. This doesn't seem right because other guides I've read say that the bearings are going bad when it makes noise. So I go back to O'Reilly's to get another one. Still noisy but quieter. But. The the electrical system starts acting up. So I go back to O'Reilly's. But. This time I get… Read complete

Same happens on my truck, if I leave it on it will come on at some point randomly. Not sure what the issue is but if I had to guess would be the radio unit going bad, going to put an aftermarket stereo in and see if that fixes it

My radio works but there is no sound at all on my speakers, they are after market Bose speakers. I don’t think the wiring is wrong either just no sound at all. What should I check first?

Remote start doesn’t work

Chevrolet Silverado 1500 2016 4door crew can 5.3 vortec 2nd  98000 miles
Remote start won’t work says I have a code (b3006 symptom 1 and 4) basically the circuit is NOT closing for the hood latch I replaced it it still won’t work this is also causing the vehicle not to sound the horn when being locked anyone have a idea

Styxxed from United States 2 years ago
It looks to me as if the hood being closed should open the switch and the bcm would not see a closed circuit. It is providing a voltage to the switch and a closed switch would indicate an open hood as far as the bcm is concerned. So just to make sure it isn't a latch, hood, switch or connector issue you could disconnect the switch, which should make the bcm see a closed hood and let the theft system work. After you clear codes. If additional tests are needed you could check at the bcm connector that it is receiving the correct open/closed input. If it is and you still are having the problem, you most likely have a bad bcm but checking power and grounds at the bcm first before calling it bad would be a good idea.

Put the key in and can't turn

Chevrolet Silverado 1500 2004 Chevy silverado 1500 0 miles
The Manuel said to wiggle the steering wheel while turning the key hard. It's just gotten to the point that it doesn't matter what you do the key will not turn. Advice please. Grandma has to get it moving I have 4 grandkids to support and get around. Someone said a toggle switch would get it going but sounds dubious to me.

Noise from front suspension when backing into street

Chevrolet Silverado 1500 2024 4x4 CrewCab short bed Duramax 3.0L RST 48500 miles
When backing out of my driveway into the street, and turning the wheel right or left, a clunking noise from different suspension can be heard. Any idea what might be causing this? It sounds like it may be a spring or maybe a shock that isn’t properly anchored. I haven’t noticed this when driving only as a back out of the driveway and the car drops about 2 inches from the driveway to the street level and it only occurs when the wheels turned. Thanks in advance for any ideas.

New battery, New plugs/wires and now I have power but no crank no noth

Chevrolet Silverado 1500 2006 Ext. Cab Z71 4x4 5.3L Vortec 189000 miles
I put a new battery in this truck about a week ago. Then a few days ago I ended up getting ahold of some bad fuel which had me stalled out in front of my house barely making it back from the store. So long story short... when getting fresh gas In the tank I figured I outta go ahead and change the plugs since I had them anyway plus the bad fuel issue figured it wouldn't be a bad idea. Then that lead to 5 out 8 broken spark plug wires which took another 2 days to be delivered. So now I get these replaced everything sound as it should be and now I turn the key, I have plenty of power from the bat… Read complete

Stuck on 4x4

Chevrolet Silverado 1500 2017  92000 miles
My truck randomly started showing a “service 4WD” and it drives like it’s on 4 high, I can barely turn. My 4x4 knob doesn’t do anything when I turn it. I had it on AWD last so that’s where the light stays but it doesn’t do anything when I turn it. (I took the #6 fuse off which makes the truck drive normal just shuts off stabilitrak, etc and of course any 4x4 option)
I’ve tried the tricks with fuse #6, I took off the transfer case motor which made a clunk noise when I took it off and I thought I was good but nothing changed. I’ve tried almost everything. What can be the issue and solution? I’m planning on getting a new transfer case control module and changing all the fluids. Any recommendations or thoughts are appreciated, thanks

CD/Radio System Gets hot, Making humming sound

Chevrolet Silverado 1500 2011 4.8l 56000 miles
I noticed that my CD player /Radio was getting very warm , The dash above it was quite warm to the touch. Also I could hear a humming sound coming from the unit. It would not accept a cd into the unit & seemed to be running the CD eject motor all the time trying to eject a CD that wasn't even in there. I believe because this motor was running all the time, even when the truck was turned off and radio off, That it was generating the heat & noise. I pulled the fuse for the radio/CD under the hood to ensure that this issue didn't run my battery down. Any ideas on what causes this and a resolution?
