    Fog Light Troubleshooting

    I think this is exactly the issue. I think the factory switch is set up to communicate with the BCM to activate the circuit. The factory switch was destroyed beyond repair, so i replaced it with a simple 20A toggle switch. I separated the 3 wires from the factory switch circuit board (which also...

    a/c compressor stays running

    Try pulling the fuse for 10 minutes to the AC, sometimes it will reset the control unit. If that doesn't work, consider replacing the AC controls in the dash.

    Fog Light Troubleshooting

    I wired them using a GM 2 pin connector, like the factory fog lights have. I do get power at the end of the wire, but only when I bypass the relay with a jumper wire. The dash light does not activate, but the LED on the switch does. The lights are grounded via the black wire provided on the...

    Big 3 Troubleshooting

    Wrong thread i assume? Check your radio fuse, and there is possibly another fuse on the back of the actual head unit. I would start there. I would reccommend making a seperate thread in the 07-14 Audio & Electronics section though.

    Fog Light Troubleshooting

    Why do I always seem to get the weirdest issues? Anyway, 2002 Tahoe. I'm attempting to wire Nilight LED pod lights to my factory fog light connectors and running into weird problems. They won't come on at the switch. I've checked the fuse, its intact. I've tested the relay with a multimeter and...

    Big 3 Troubleshooting

    Here is the diagram I used for building mine. You may need all 4 wires, or just 2. If you face the back of the alternator, your 4 wires from left to right are PLFS. Pulse, Lamp, Field, and Sense. Lamp will be the spliced wire on the harness. It's important to note that you do not want to connect...

    Big 3 Troubleshooting

    The 104 Harness has all 4 of these wires, but I only needed two of them, the Brown (F) Field Wire , and the Blue (L) Lamp Wire. The fuse tap comes off of the Lamp Wire. The female end goes to the factory alternator connector on your Tahoe, male end goes to your alternator.

    Big 3 Troubleshooting

    SOLVED: The issue was with the LAMP signal wire, otherwise known as the L Terminal Circuit. GM did not implement RVC (Regulated Voltage Control) in their 1500 platforms until 2005, this means that the voltage was controlled by a regulator built into the alternator, rather than the PCM itself...

    Big 3 Troubleshooting

    Hey all. I recently did the big 3 upgrade, but I'm running into a strange issue. I have a dual battery setup with a battery isolator installed, which works just fine. At the same time that I did the big 3, I also upgraded my alternator from a 130 amp to a 250 amp. Before doing this, I had a...

    4L60E Information Thread (Includes 4L65E/4L70E)

    Finally found this thread. A few questions for ya. 1. What would happen if you were to leave the filter out of the TCC solenoid? What symptoms would occur if this happened? 2. Could scarf-cut teflon rings on the pump stator cause a cross leak and a total loss of transmission pressure? 3...

    SOLVED: Please help identify this noise

    Check your clutch fan/electric fan to make sure its not making contact with something. I had a piece of my fan shroud towards the lower half break and barely touch the fan blades on start up, once the fan built up enough rpm, the noise would stop from the air pushing the piece out of the way.

    SOLVED: Please help identify this noise

    What year make and model is it? Is it causing you any problems starting up, or driving? Based on the little information I have, i would say either a dying starter or fuel pump.

    Western PA Chevy Group?

    Just wondering if anyone knew of a Western PA Chevy truck group (Beaver County area). Been working on my trucks alone for the past 7 years, kinda tired of it. Trying to make some friends in the area to exchange help and advice. I have a 2003 2.2 S10, a 1996 AWD Blazer, and my project truck is my...
