Our 04 suburban has had the dash lights on (and window power etc) after removing the key and opening the door! Replaced the ignition switch and lock cylinder, looked at ground wires on the frame, didn't redo any of them because we live in the NW; they didn't look rusty (but should I have anyway?) The problem is intermittent, sometimes the dash lights will go out after the key is removed and door opened, but usually we have to disconnect the battery every time we park, we installed a knife switch a few months ago. It also idles roughly and takes 3 or 4 seconds to start sometimes, I've always attributed this to the battery being recently reconnected and the computer having to relearn everything... in recent days the dash lights have been going out properly, so we haven't had the battery disconnected in several days, and the car still runs badly and no engine codes. Thanks very very much for any help! Ben -
U0100 Lost communication with ECM U0073 CAN Bus Communication P2544 Transmission Torque Request Signal Message Counter Incorrect P0700 Transmission Control Module Requested MIL Illumination P1682 Ignition 1 Switch Circuit 2 Good Morning Yall, Long time lurker, first time poster as a member, and really appreciate this forum. Recently the past year I have had some symptoms that didn’t affect the drivability of my 2014 Silverado z71 4x4 5.3, but were very present on a random basis, especially during rain. Service Stabilitrak, Service Trailer Brake(nothing being towed) popping up the screen, sometimes binging back to back for extended amounts of time near to 30 minutes frequently. Today the truck would not start, and presented these codes above under a check engine light. The truck started after having the battery disconnected for 15 minutes and has started since so far the previous 12 hours. Also while driving and the typical service notifications, one headlight being out, the truck engages the transmission at a slow roll/acceleration and a very very rough/lurching, almost feels like being rear-ended engagement, it would not engage power steering, and also presented a warning of reduced engine power. Some of these symptoms of course seem to be directly related to the codes, but seem to have progressed as time has gone on. One issue noticed was a tail light having a small crack, and a sliver of water pooled inside of it. I am unsure if that may be related to the issues present, but I have ordered new lamps. I have also previously installed a new ground cable from the battery to the block, and also verified the ground on the driver-side front beneath the dash/tweeter. The battery also tested good, so did all of the fuses on the battery side and the box side with the voltmeter. I have not checked the starter or alternator, but they are less than a year old. Any help or suggestions would be greatly appreciated. Sincerely, Ben -
My 09 silverado 5.3 4x4 has shifted hard into 2nd and some into 3rd for several years now. A few months ago I decided to fix it. Codes were for transmission control solenoids, module, oil pressure sensor, misfires...etc. codes like P0700 P0717 P0521 P0523. I replaced all 3 shift solenoids, oil pressure sensor, and immediately the truck shifted like new again and it lasted for a few days or a week. And it started shifting hard again. Really hard. It's so frustrating. And it's throwing all the same codes again. Recently, my truck started misfiring so badly the entire truck was shaking. It was running on two cylinders. All of the ignition colis were failing all at once and the truck was not drivable. Btw, I just changed out those ignition coils, plugs and wires just two years ago, all Ac Delco plugs/wires and duralast ignition coils. So anyways, I replaced all of the coils plugs and wires again this week and the engine no longer misfires, running on all cylinders again. And for a few hours after, there was zero hard shifting now. It was running great, like new again. Shifting smooth as could be. But after making it into the city and hitting traffic lights and stop signs, it didn't take long for the very hard shifts to come back. I've read on this and have been dealing with this in time and parts for so long now. I've read about ground wires could be the cause of all of this. I have replaced everything the computer has suggested, and for a short time after the repairs, the truck would run like new. But the hard shift always comes back. I know there's people out there that have had this same problem. I've read a lot about it but without actually finding the grounds for these specific sensors, I've hit a dead end. The issue just keeps coming back as it's obvious there is a root cause I am not getting to. Please share any knowledge or experiences on this topic. And any knowledge of the location of these grounds may be at. Thank you!

First time posting but have searched the forums for years and have always found what I needed. Well this time I'm stumped, so I have a 1994 gmc k1500 pickup with a rebuilt 350 tbi bored .030 out with a stage 2 cam and long tube headers. (About 4000 miles on engine.) new distributor, plugs, wires, vss, So here's what's going on, the speedometer jumps around super erratically but when I turn the heater on it seems to change how much the speedo jumps around. If its on high it jumps around the least. Low or off its just bouncing off 85mph like bouncing to the point I can hear it slamming into whatever stops the needle from going any further. When I turn the turn signal on left it makes the radio light dim with each flash. The odometer turns constantly when while sitting in park. I have replaced the vss at the very end of the trans where the rear drive shift meets. I was drive the other day and the truck just didn't want to move seemed like it was just constantly back firing or misfiring. I have been trying to check all the engine grounds but not sure what all needs to be grounded. Any info/advice would be greatly appreciated. -
Hello. I have a 1995 1/2 gmc sierra k2500. I have intermittent ABS & Brake lights in dash. I also have 4wd not functioning. I also have malfunctioning heater. On one schematic, it looked like they all go through ABS unit. ABS unit is sealed and unable to come apart to resolder connections (cannot unseal unit for reflow repair). Obtained used ABS unit. Tried to redo chassis ground. Supposed to be located under drivers door. That ground is non-existent. Was never there. Who knows where the alternate ground spots are for this vehicle. I'm adding ground strap at ABS unit, down to frame. Want to find original ground. Heater has all new components. Loses power at fuse box when put under load. Need help. Please. -
I just bought a 1991 Chevy C70 Kodiak C7H042 6.6L 403 CUI Diesel in amazingly great condition. I am now the 3rd owner of this dump truck. The first owner took great care of the vehicle, everything thing appears to be well maintained and no shade tree work. All the parts, wiring and accessories appear to be original and well maintained. However, the second owner bought this truck and never used it. It has sat in a field for about four years. To get to the point, I completely serviced the truck and replaced the batteries, checked the fuses, grounds, relays and I have absolutely no power to the truck. No interior or exterior lights and no lights on the instrument panel. What could be the issue?

From the album: MoriMoto - Mopar HID Upgrade
I need to move this to somewhere else, as my HD radio instantly goes into search mode when I turn the Headlights on.
