I have an 04, I have no low beams, high beams will only flash, no fog lights, but parking lights all work. What may be the cause. I know fuses and relays are all good. I have a new headlight switch on order but not sure if that’s really the issue or if it’s the fuse box itself.

Hello , new to the group thanks so sorry if I’m posting to wrong group or if question has been asked before. My issue is that I bought a ‘15 1500 WT 5.3L that had around 350k with lazy #7 cylinder. So I bought used motor with around 100k from a ‘15 gmc 1500. Swapped motors out and when I went to start up I don’t get any crank, No gauges work, service error lights all come on. I’ve checked to make sure grounds are clean and tight, checked fuses inside cab and in engine bay, battery tests good, getting codes U0100 and U0102 and I’ve also installed new: -Engine Harness (found some splits on harness that came with motor so bought new one) -Computer (also have the original and one that came with the motor and I’ve tried swapping all 3 to see if that worked) -Relay panel in engine compartment Just seeing if anyone has any fix’s or tricks. Thanks

Hello, for the past two years my truck (2015 Sierra 1500 All Terrain) has been intermittently flashing service lights saying the to service ABS, to service stabillitrac, and to service parking sensors. This would happen a few times a month and would immediately go away and I would think that it was just an annoying bug. But since about a month ago, when making low speed left turns, as well as any size bump, caused it to happen. This worsens into ABS light and stabillitrac light on for one day. While this happened you could feel the ABS pumping at when braking normally. This too went away the next day. I took the truck to the dealer for a diagnostic and told them all of this as well. After the $190 diagnosis they said it was the following codes (attached photo) C0035-04, C0040-04, and C0035-0F. they told me both front hubs were bad and needed replacement. They wanted $1800 for parts and labor. I told them thank you and paid the diagnosis and took the truck home. After the dealer the trucks electronics and 10x worse. Now the ABS and Stabillitrac lights stay on permanently, the brake light dings and flashes with any turn of the steering wheel. Also getting constant service ABS, service trailer brakes, Service stabillitrac, and reduced steering assist. I bought both front hubs and wheel speed sensors. I installed them and torqued everything back to spec. After reconnecting the battery and taking a test drive nothing had changed. I took the top panel from the dash off and did the ground mods. Again, no change. I’m going crazy trying to find the problem. I the. Took the truck to autozone for a code read. It still says the same three codes and it did, even after replacing the parts and sensors the dealer said would work. If anyone knows what the cause is it would be much appreciated. Thanks in advance, Dave

2011 Chevy 1500 LT crew - 144k miles So, after countless hours of searching, I’ve decided to post here in desperate need of help. My truck is currently in the shop, and on its 3rd mechanic trying to diagnose/fix the issue. Originally I was getting an oil pressure sensor unit code months ago, and about a month of driving later, and I finally lost my oil pressure gauge (dropped to zero) but the truck was perfectly fine. No loss of oil, etc. So I brought it in to get it fixed and change the oil - they put an OEM part in and changed the screen. Reset everything and I picked it up, a few moments later my check engine light returned. Scanned it when I got home, same error code - active. Checked for oil leaks, etc - nothing. Returned a month later for them to fix it, they put in another OEM part and new screen…drive it 3 miles down the road, and it trips again. They’ve checked the valve cover gasket and checked the PCM, everything seems fine. The truck is not burning oil either. I’ll add that my oil pressure gauge on my dash works fine now since they swapped sensors too. Everyone is stumped on what to do, and I’m about to potentially go down the rabbit hole of ‘throwing parts at it’. Starting with the PCM and then the valve cover gasket, and many thousands of bucks potentially. Does anyone have the slightest idea what’s going on? The PCM is throwing no other codes either, he has graphed and checked it. Is it possible for the PCM to be corrupt without it giving errors, etc? The tech is a 30 year vet, and a family friend - so by no means is he stupid. But this has stumped two other techs with equal experience too. Now my truck is past inspection, and with my Check Engine light on, it’ll never pass. Plus I’m still half way on my loan, so just selling it isn’t an option. Help!!!! -
Does anyone know what this grey connector is for above the overhead console, it is attached to the console, but the plug is empty

98 Sierra 1500 5.0 vortec 4x4 SLE ext cab 295xxx Ill try to keep this short, any help appreciated thx in advance. My front signal and head light started doing all sorts of weird things head lights flashing with 4 ways, left signal wouldn't work with head lights active. The interior lights where acting weird. Work sometimes. The cluster gage illumination would not turn off. And there was nothing to rear rail or third break lights. Also some funky noises coming from the combo light relay So I thought it was ignition harness, cluster,dimmer switch relay. All fuses where fine. But my cig lighter fuse keeps blowing. So I went to junk yard and grabs some parts. So I tested battery and all the grounds I could find and cleaned them. As a changed parts nothing changed. So I was checking the wire harnesses and found that on the wires that runs back to rear of bed on driver side frame was melted up in spot and arking against the frame. So I patched the wires. Now the truck wont start and no lights will work. If you press break peddle the signal light on cluster light up. But not actual signal lights and if u try to turn fan on it turns the signal lights on cluster on and as ur turn it up the lights get brighter and my interior light on driver side floor won't turn off. All fuses seem fine beside the cig fuse. I'm out of guesses.
