My truck is stuck in 4hi when I turn the key on service 4wd light comes on. A when I push 2 hi it flashes. tccm clicks then I hear a humming/buzzing coming from the to shift motor an stays in 4hi I can push 4 auto an It goes into that but no 2 hi or 4 low I have two 99s so part are easy to get so I swapped out the dash switch with a working one from my other one. No change . Swapped out them (transfer case control module) no change. I believe my actuator is working as it should I hear it just like my other working 99 4wd system so I thought it's gotta be a bad shift motor but after reading lots of posts here I'm thinking a bad wire? Any input welcomed to have an appointment at the shop the 7th of July if I can fix it before then I'll save 200 bucks what colors are the problem wires that every one has? An is there a way to get it into 2wd if i cant fix it myself?
I haven't check my fluid yet I haven't run it for codes I tried but the checker didn't have the stuff to get to transfer case data
Silverado :: ABS Light Comes On But Brakes Feel Fine
This is on my g/f's 04 silverado 2x2 started about a month ago. Light comes on after rolling a few feet and right after hearing the abs pump run for a second. Then the light pops on, but the brakes feel fine. Only thing I tried so far is to clean the ground wires under the drivers seat but it's still doing it. I know when my sensor(s) went bad on my 00 the abs pump would kick on when stopping! not fun at all, but like I said it stops fine, just the little pump hum then the light.

Silverado :: 2003 - Check Engine Along With ABS Light Was On
I have a 2003 silverado 1500 4x4. The check engine was on along with the abs light. I went to advance and let them tell me what was going on. I don't know the specific code but it said the passenger front abs speed sensor was bad so I replaced it along with new brakes, rotors and calipers. Now the abs, check engine and red brake light is on. There is also a message telling me that the brakes need serviced. I went back to advance and let them tell me once again why those lights were on and it was still the passenger speed sensor bad. What could be going on with it? Before it was replaced the red light never came on but now it is.

I purchased the vapor canister vent valve and purge valve as the service engine light has been on and this are the contributors. I want to know the location of these and how to access. It appears that they may be by the fuel tank and I don't know if I need to lift the box or something to access them. It is the 5.3L V8.
View 5 RepliesSilverado :: 2000 - No Headlights And Security Light Staying On
I have a 2000 Silverado 1500 4.8 liter v8. On my drive to work this morning the headlights and the cluster light shut off and the security light illuminated and has been on ever since . The truck will crank and run fine I have brake lights and turn signals and reverse lights. I have read that this problem can usually be traced back to the body control module. I located the TBC fuse under the hood and it was blown. so I replaced it with another 10 amp fuse and it blew immediately after I inserted it. So I am thinking if I am able to rule out a ground or bare wire somewhere then the module itself may just have to be replaced.
The next question I have is due to the security light staying on in the cluster all of the time. Assuming that I can continue to drive the truck while waiting to have the BCM replaced I would only need to ensure that I did not drive after dark as I have no headlights. But I am concerned that the security light being on all of the time will drain my battery. Do the security light remaining on will in fact drain the battery? And if so, is there a way to disable the cluster and door security light so that I may continue to drive it and not have to come home and disconnect the negative cable every
Silverado :: 2000 Chevy Truck Won't Start - Security Light On
I have a 2000 Chevy silverado. I recently was having problems with the transmittion not switching correctly. Long story short the shop told me to fix the problem I had to put in
A new transmition as well as a new computer which I did, from another Chevy. It worked for a few days then The truck was not starting and had security light on. Had alarm specialist take look and he said the computer had to be reprogrammed. It was reprogrammed at merles. And was still not working. Its unable to start, starts at random once in a long while. ignition switch was changed and still gave same problem. Took to another shop they had a specialist take a look and he said the computer had to be reprogrammed again.
Also would it be possible to bypass the anti theft system by adding a remote start, or cutting some wires. I just really need to get this truck running.
Silverado :: Check Engine Light Came On - Mass Air Flow Sensor
Ok so I just replaced my mass air flow sensor about a week ago. My check engine light just came back on and when I scanned it it said mass air flow sensor. What could be causing this to happen again? The codes are P0102, P0440, P0440.
View 4 RepliesSilverado :: Check Engine Light On / Sound Skips On The Radio
First of all, its 5.7L V8, it's been very well maintained, I've had my fair share of problems but nothing that has been that serious, except for the "check engine" light for the O2 sensor.
For about the last 4 months i've had the problem of the truck sometimes jerking while on the road. Once i started to speed up it seemed to not speed up which when it did, it jerked a bit. That was in the beginning.
AS OF NOW, the jerking has stopped but every now and then when i pull out of the garage and start to turn onto road it turns off, but all the status lights are left on. & when turn the key to turn it off and restart it starts again every time. Ive noticed that i was better off with the "check engine" light on then now because every time it is off it has these problems.
Also, when I barely start to tap the brake, again not all the time, sound skips on the radio. & this always happens when i tap on the brake & this happens more frequently when the "check engine" light is off.
Chevrolet - Silverado :: Shaking While In Idle / Check Engine Light Came On
I just bought this used truck, 2005 Chevrolet Silverado 1500 extended cab. I noticed some shaking while in idle when I got it back home. The check engine light came on a day or two later, and I recently had a diagnostic test ran on it at the local AutoZone. It came up that I had a P0135 o2 sensor (bank 1 sensor 1) malfunction and a P0101 Mass Air Flow Sensor signal performance issue. The check engine light comes and goes. I stopped by Walmart for about 10 or 15 minutes and when I got back into the truck, the issues reoccurred. For about a minute, the check engine light actually started blinking! And then went away and started running normal again. Its upper confusing. I bought some MAF cleaner to use on it tomorrow and figured that wouldn't definitely clear up my issues, but I'm still wondering if the MAF sensor is enough to warrant the CEL to blink like that?!
View 6 RepliesSilverado :: P0307 - Check Engine Light Comes On When Going Up Hills / Under Heavy Load
I have a 2001 chevy silverado 3500 6L gasoline engine.
I have been getting a P0307 random multiple misfire #7 on and off for a few months now, occasionally the P0300. Check engine light comes on when I am going up hills, often under heavy load and sometimes when the truck is cold in the morning and the truck starts to run rough until the code clears, which it does pretty quickly usually. I have replaced coil, crank sensor, cam sensor, fuel injectors. If I unplug the battery overnight the code will be cleared and the truck will be running just fine the next day.

I have a 2001 1500 with the 5.3V8 motor (ext. cab sb 4x4 LT). I was my dads and had the service engine light on for a long time for the P0446 code. I replaced the vent valve and the purge valve and light keeps coming back on. Usually can go for a day or so and then it comes back on and I get the same P0446 code.
View 3 RepliesChevrolet - Silverado :: 2002 Power Loss And Service Engine Soon Light Blink
Driving while in 4x4 HI up a hill the truck started to slip. I stopped, shifted to neutral, and engaged 4x4 Low. I shifted back to drive and started moving up the hill. The engine started to lose power and the "Service Engine Soon" light began to blink. I put the truck in park. As I let it run a little bit, the engine started to shake as if something was very imbalanced. I went to check under the hood, and confirmed that it was shaking quite noticeably. There was no grinding or clattering of any kind though.
I turned the truck off for a bit, and then restarted. There was no light or shaking upon starting up; but as soon as I put it in gear and started driving I could tell it was losing power, the light came back on, and the shaking ensued. This occurred in 2wd, and both 4wd lo and hi. I parked it at a neighbors place and there it sits for now.
I plan to try and get the codes read. My other vehicles can't make it through the snow we have right now, but it is suppose to get warm later today and might melt enough for me to get one out. I also live out in the country, so the nearest auto parts place is about 20 miles. Same with a dealership service shop. I'm hoping I can buy and return a code reader from an auto parts store to assess if this is something I can diagnose myself or not.
It is the 6.0l gas engine with the 4sp automatic transmission. The truck also has about 107,000 miles.
Chevrolet - Silverado :: Check Engine Light Comes On After Intake Manifold Gaskets Replacement
I have a 1998 chevy silverado z/71 4x4. I had a water leak and had the intake manifold gaskets replaced. Ever since then, the check engine light comes on and it soots up the o2 sensors and the 4 plugs on the right bank. It may run good for a month or so and then it starts all over again.

View 15 RepliesChevrolet - Silverado :: 1995 - Driver Side Tail Light Turns Off When Hit The Brake And Headlight On
I have a 1995 Chevy k1500 Silverado Z71, I am having problems with my tail lights where when my headlights are on and I hit the breaks the driver side tail light completely turns off, if I use the left blinker it blinks very fast up till I hit the breaks. When my headlights are off they still don't work properly but legal enough, the left blinker blinks in between fast and slow and when I use the brakes the left side works but very dim, the wiring is all original never tampered with, all I did was put aftermarket tail light covers on it which shouldn't affect anything. The problem usually comes and goes but this last time it lasted for 2 months and now everything works perfect, the problem will be back and I'm afraid I'll run out of luck and a cop will finally notice it.
