Watched 3 times and didn’t see anything about PCM ground, I have a PCM code 1518 and many sources say it could be a ground issue, would you please post the location of PCM ground? Thank you and thanks for the great video, I’m saving this one.

Thanks for reviewing all grounding points.

Wuzup, bro! Big fan of the channel, no problem supporting it. You saved me alot of $$ and time.. would a bad ground cause the ac not to come on, already checked the fuses and relays. I'm stomped

You were so close to the areas of the grounds I could not see what part of the car you were at. It would’ve helped if you would’ve had a laser pointer or a sharp flashlight beam to be more specific.

Thanks bro you saved me a lot of time

Glad I found this video great video, I'm new to the C5 world I need more videos like this I'm having some issues electrically. Lol

Thank you for reviewing these grounding locations. Ground location #3( G401) is actually best accessed by removing the rear drivers side tire. It is connected to the frame rail directly behind the tire.

I need to do an updated version of this video with better lighting & showing the points (I had the car torn apart about 3 times now). I'm glad it was helpful! 👍🤙

Great video man saves me a lot of time trying to help these guys online haha

Dude. U just saved me so much time.

I've went through most all of those to troubleshoot my speedometer not responding. I bought the factory service manual. I also discovered my PCM is ungrounded in the process. Troubleshooting that I find S120 and G120 are where the PCM grounds. However, I cannot figure out where those points are... The FSM doesn't specify. Ug. Any help would be appreciated.

Should I add dielectric grease after i clean the surfaces, before I tighten them back up?

Thank you so much. Been having problems with Gauge cluster, radio, and wipers. Going to clean the ground on Driver side foot panel. Just cleaned the four cowl drain bladders, and think my grounds may have gotten corroded.

@@timothyandemerald If your looking for the ground, it's between the door jam and parking brake release. You have to remove the plastic cover that covers the bottom of the door opening and the inside cowl.

What could make the gauge lights turn off as soon as the motor is on? They turn on when I unlock the car and when I turn on the ignition they are still on. So they are working. But as soon as the motor starts they turn off. 🤔 They are off regardless of whether or not I have the headlights up, but they did turn off the first time when I touched that lever. Can't remember if I turned on the headlights or cruise control or what, but I heard a short quite "beep" sound and the gauge lights turned off. Since then I can't get them to turn on when the motor is running. 🤔 I just boight it the other week. The former owner said that the fog lights stopped working the last time he washed the car, and that it keeps blowing fuses since then. But for me, everything else has worked until now, including all lights, until this gauge lights issue occured suddenly. 🤔

Which ground controls the button to release your tonneau cover on convertibles ?

Very useful video that no one else will do. But very hard to see because so much in camera shadow doing it alone. Need a helper to hold light and point at splice pack with a dowel. A bit too close, so hard to understand what part of frame I'm looking at. On my C5, the problem was grounding between the frame and the splice block just as you say.

When I press the brakes, the radio goes into dim mode as does the car. Any ideas which ground that would be?

Which ground is the one for hvac unit? 97 c5 dual climate control. My hvac unit display will sometimes just die out then randomly come back on. It’s been doing this for a bit but now seems like it won’t come back on at all even after an extended period of time. I replaced all hvac fuses just incase under the passenger seat. Any help would be really appreciated!

i mustve missed it but where does the throttle control module, pcm, and bcm ground to??

How about the battery (brand new OPTIMA) dying every 5-6 days?? Could one of these be the issue ? No other symptoms and it seems to charge as it will restart and if I start daily - it seems to be OK. Just do not have the time...

FYI, there are actually 13 grounding points on the C5. The two behind the radiator on either side or plugs that need to be taken apart and cleaned also.

Absolutely. Plus there are two white ground wires on the back of the drivers side rear head. You have to remove the intake to get to it. Good video but still incomplete because they’re 13 grounds not 9.

I have 2007 C6 base and can't find the grounding point for the left turn signal. HELP ! 🙏

you're missing the ground points under the pass and driver side headers that go to the block. Ive had fuel pump issues when the driver side ground under the header ground wire was loose.

Thanks this was needed

Curious- Radio Shack? I haven't seen one in many years. Not even on line. Good video though for the 9 most common grounds of the 13 total ground points.

Did I miss where the Front lights ground too? Specifcally the driverside turn signal?

I have tail light issues. Idk what to do. Brake light works but taillights don’t ugh.

What ground is associated with throttle position sensors?

It started with clicking noise, i replaced starter because battery is good 13.2 Volts. After installing the starter I, It turns over nicely, but won't start. And I have a shit storm of codes, LIGHTS; Check Eng, ABS and Traction Control. MESSAGES; 1. Reduce Engine Power 2. Check Tire Pressure 3. Service Engine Soon. 4. Low Fuel. When I went to look up codes; all of them 40-BCM NO COMM, 58-SDM NO COMM 60 IPC NO COMM. All of them NO Communication. I pulled ground the 4 smaller ground wires, cleaned and reattached cleaned all of the ground wires associated with this issue. My questions is could it be the ignition or the PCM or PCB?

I found one ground strap on the drivers side from the frame to the engine block is green(oxidized) it can’t be helping. I am leaning to either a security issue or a bad ignition switch.

If the rest of your cluster has power most likely not not unfortunately as they all run off the same ground. I read somewhere some time ago that the speedo's on these tend to go out. Throwing in a new one isn't terribly hard though.

Went through the same issue a few months ago. The problem was in the ignition tumbler. The 'chip' in your key is actually a resistor. Take your key and measure on the ohm setting of your multimeter. There are 15 different keys for your Vette. Figure out the resistance your key is supplying to the VATS. The fix for me is pulling the VATS connector off the back of the ignition tumbler. I went to Radio Shack (yes, we still have 2 in New Jersey) and purchased 2 resistors that equalled the amount of resistance needed for the VATS. I soldered them together and 'plugged' them into the plug for the VATS harness and taped the shit out of it with electrical tape. Put the key in the ignition and it fired right up. Total cost of the fix was around $4. LOL

Heads up yall: I tried doing the "accordion jiggle" at first and it wasn't working for me. you need to pull the accordion out and to the side, and shake the fuck out of the cable itself and it should fix - at least temporarily

I appreciate the effort, but it would've been better to use a laser pointer/flashlight. The locations you mentioned are very vague without a pointer. Nice try, though....
