Greetings Ya'll!!!! I just noticed, as I was seeking data about My "Possesed Van", the majority of Posts are old, if not "Very Old". Am I the only one in America, having issues with an older Chevy Express Van?

Greetings Sarge! I reckon that it's going to be whether a Van will keep what You are hauling, out of the weather, & organized better than a pickup. Myself, being an HVAC/Elect/Refrig Contractor,need a Van.

Greetings Jsdirt, I have to apologize, I just saw your reply, & I never got a notification about any reply. With My & My Son's work,& many other issues, we've made very little progress on working on my van. Today, I learned about a ground location, via a video from "Etrailer" about how to install a "trailer brake controller", as well as the ground wire & hot wire color that feeds the brake switch, & I'm hoping to get back over to work on the Van, & ck out these grounds & wires, work permitting, early next week. And I appreciate your help Js!

Thank You C/KMan & diyer2! I'll look in to the Manuals for sure. What's been baffling me is how the radio quits working while all of this is ongoing, .... Other than possibly a Common Ground, do Ya'll know if whether the Dash Cluster also controls the radio? And again Thank You!

Greetings C/K, Do you know of any GM Document, on Th' Net, that gives the location of the Frame, Body, Dash, & Motor Grounds? And, I've not replaced the Dash Cluster yet, and I'm thinking that it has more to do with a Ground,due to the Radio operating erratically, & that it everything goes back to normal when the brake pedal is depressed. And, I'm going to hunt down that Factory Shop Manual that You mentioned.

Greetings Ya'll! This is my first post & more than likely there will be many more, as I rebuild my van I bought a wrecked in the front end 2007 Chevy EXpress G2500, & after having straightened the frame, replaced the bumper & grill, lights, & hood, the Dash Cluster Gauges, & Indicator lights which had no problem before, then began to operate in an insane manner! The Temp., Oil, & Battery Gauges would rise & fall, & the "Security", "Check Engine", would go on & off. I put a "load" on the system by tuning on the headlights, heater, & radio, but they had No Effect on what was happening, BUT,...... when the Gauges fell to 0, the radio also quit working every time, but the Heater Blower, Hazard lights, & Headlights continued to operate with no problems. I found by accident that by pressing on the brake pedal, & releasing it that everything would return to normal, including the radio for about 3-5 seconds, but then the "Van Possession" would then return. Again, nothing happens to the Hazards, Blower motor, nor Headlights. Now here's Th' Kicker,... When I depress the Brake Pedal, the Dash Cluster works perfectly. When I release the brake pedal, then within 3-5 seconds the Dash Cluster & Radio then start the whole insane process over again. Has anybody experienced this, & if so, how did you fix this nightmare? Is there a ground that may have become disconnected during Our Repairs, that is specific for the Dash & Radio? And, can anyone tell me where to get the Dash wring diagram?

Greetings! I'm rebuilding a 2007 Chevy Express G2500, that had been wrecked in the front end. We've straightened the frame, replaced grill, bumper,& hood. Prior to this work, the Dash Cluster operated properly, but,... After getting the above work done, the Dash Cluster Gauges would come on, & then the Voltage, Oil, Temperature gauges would rise & fall, & the "Security" & "Check Engine"& "Battery" indicators would come on & then off. Putting a load on the Van, by turning on headlights, Flashers, & radio, has no effect, BUT,.... When the Gauges fall down,... The Radio quit working. I stumbled in to learning that when the brake pedal was "Tapped", that everything would return to normal, but within 3 to 5 seconds, the "Possession of the Van" would start all over again. I then found that by putting slight pressure &/or pressing the brake pedal, that this issue disappears. No Fuses have blown, & so far, I have not found any wire,directly making contact with the brake pedal assembly, neither under the dash, nor at the firewall near the Brake booster/reservoir assembly. Do You have any ideas, any data, or any sources that you could direct me, so as to solve this problem? I am familiar with a Service Bulletin that had been issued via GM, that was addressing an issue similar to this, with part of the problem being in the wiring harness close to the "Brake Switch", but, have a problem in locating that Bulletin in the many files/Downloads/Videos that I have saved for my van.
