We changed the transfer case and now it says service 4 wheel drive and when you change it to 2 wheel drive to four wheel drive it doesn't light up. Any ideas?

I pulled out the bulbs so I did not kill battery, just arrived at hotel for my vacation. Been reading blogs how others changed with and still have same problem

Have been to local parts house they plugged in diagnostic reader. several codes came up. Long list of codes. U1000, U1016,C00055, C0Z01, U1255, C0550, B0790, B2725, P0380, P0540. Do not notice any thing wrong with vehicle starting driving nothing, but from codes WTH???? Is the main PCU bad ??? One of the codes refers to the dash cluster and all gauges are functioning fine. As well as every thing else seems to no problems ?? Please advise.....

I just bought this truck last Friday and towed another truck on a dolly with it from New Hampshire to Springfield mass with no problem now for two days it's been saying engine coolant hot why is that could it be cause the cluster doesn't work properly I just ordered a new one

How do I diagnosis the cause, what's the repair and cost

The exhaust manifold bolts all the way in the back of the manifold, are breaking off, causing the exhaust to leak, is there any reason they are breaking like this?

Driver door also changes position when key is taken out of ignition

happens mostly when fuel is low or when motor get up to temp.

the tag lights does also . is there a elect ground on the truck

I am going to replace front hubs see if that is the problem

It happens every time I floor it if I don't floor it it stays at 80. It has always been between 40 and 50 what could cause it.

I have a 02 2500 hd. It has the manual shift option for the 4 wheel drive. My fuses are good and just changed the front acuator. But it won't shift into 4 high or 4 low. I have no power to the front acuator

I have replaced a broken brake line, the master cylinder, and one caliper. I have bled the line several times to no avail.
What else can it be?
Thanks Marv

after I bleed it off it may go 2 or 3 days before it does it again could my abs be doing it?I have replaced the rubber hose and brake pads turned rotors and replaced the clap.

No crank problem.
Found blown fuse and replaced .
Fuse blew on first try .

Sometimes like factory key will turn the ignition sometimes it's locks in place

First of all, GREAT site Thank You.
Truck was stored for 4 years, ran fine previously with 56000 mi, started 3-4 times in yr. Fuel pump went bad and bad gas in tank. All fixed, after awhile p0300 , the only code,came on with a noticeable miss, worse cold. Runs good at speed and accel. Cyl # 4 fouls quickly. miss worse on even side, #1 with only a few. 3-5-7 quite a few. Cleaned MAP & throttle body.Compression 140psi. Checked wires, coils run @ 35-40kv, even though at 2500 rpm they all went down to about 10kv. It was an old scope and had to ck each cylinder individually. swapped coil #4 & #1 no change, exhaust pressure before cat on even side .65psi. Pulled injectors on even bank looking for leaky ones. All held pressure@ 75psi on bench test with good pattern. With EZ-scan tool 6000 A/F ratio 14.6. I have the scan tool results, if they could be of help and perhaps someone that is in the know may be able to come to an conclusion. Thanks Doug

Started truck and quickly moved it to garage and shut off before it warmed up. Replaced all coils and tried to start engine. Engine fires but does not start. Throws a code po446. Possibilities?

I changed the blower motor a few months ago. I changed the blend door actuator , charged the system and still it blows out hot on passenger side. I hope it is not what I think it is, that's a job

Whenever my seat belt is being used, it continually squeaks.

200 Chevy Silverado 2500 HD won't start. Outside temp is not really an issue. Ran fine yesterday. This morning it cranked but wouldn't turn over. Tried turning the key three times and it finally worked. Now it won't start again. It sounds like it will turn over then it just doesn't.

I have had the worst luck with cars. Lately every single car I get into has broken in someway, shape, or form. I really hope it is just a dead battery.

If anyone knows anything or has an idea of what it could be please help!!

? Intermediate shaft, pitman arm? Someone suggested putting the expanding foam into shat and reassemble?
