Hi! How can I resolve an error code B0004 on a GMC Savana 1500? It's a 2007 model with a 4.3L engine.

Twice my fuel gauge has rotated past Full. Today I went to a GM service dept with the gauge reading at 5pm when it should have been about 3/4 full. They did a diagnostic and advise the cluster of gauges had a problem. When I got back in my truck the gauge now read 3/4. I stopped and filled the tank and it is now reading full as it should. Service manager advised to drive it and see if it fails again and if it does we all know it is going to cost $513 to replace the cluster with a re-manufactured cluster with a short warranty and labor, all costs $513. I don't understand how hooking up the test equipment could reset the or have the gauge show the right fuel level. I love my truck and plan on keeping it for another 5-10 years as I only put on 5k miles a year and the truck has 60,000 miles now. Should I wait to see if it fails again or go ahead and get it replaced for $513.00. Confused on why the gauge changed by them testing the computer. thanks, JJ.

Hoping to disable the passenger side airbag on my 96 GMC Savana Explorer. Is there a switch somewhere? Can I just pull a fuse?
Hoping to do it without taking to a mechanic.
Thanks!

Turns over about 30-40 times than fires once but won't start. Won't even fire on starting fluid.

Happens intermittently. Suddenly no air flow from any vents. No heat or AC.

But When I Manually Turn On the Headlights...The DRL's Stay On With Headlights? Anyone Know why? Thanks for your answer.

This always happens while running. whether parked & running or while driving. BUT, If I turn my headlight switch ON-Manually...The Headlights (both), stop flashing and stay on. "What can be wrong?" Are the headlight wire harness' Blown? (Says Manual) or what? How Much should a repair like that cost?

It almost sounds like something falls over in back of conversion van. this is new today!

the small lights in the step wells still work. checked all the fuses. it is a its a santafe high top converson. they just stoped working after sitting for a little while

Van has been intermittently having rough start and white smoke from tailpipe for months now. Van had complete tune up and new distributor at 96,000 miles. Symptoms started soon afterward. Van has never overheated and always runs on cooler side. Coolant overflow reservoir is often needing to be topped off. No external leaks detected and radiator/water pump/thermostat/hoses were replaced due to age last year. Van just started misfiring on freeeway very randomly. SES light comes and goes. Last time it was on, Pep Boys said it was misfire on Cylinder 6. SES light not on now. Van drove nicely down to shop...mechanic says, just based on fact that it is using coolant somewhere and puffing white smoke upon cold start, that it must be the head gasket. He has not done compression check or anything else to diagnose. I am tempted to put some kind of Stop Leak in, since the symptoms are so intermittent and because he does not want to work on the van. Any thoughts? What kind of Stop Leak is best? Van will start and drive just fine some days, with initial white smoke upon start up that clears up when you start to drive it. Other days, it misfires. There is NO oil and water mixing, and the van NEVER overheats and NEVER has, in 30,000 miles of owning it.

When I put fluid in it runs out the bottom. not sure it its reservoir or attachment. how do i access to determine?

After I shut it off and wait a couple of minutes, I can restart it and use it the rest of the day. Turn it off, restart and drive for hours with no more trouble.

The gauge for oil pressure shows the usual 40 but the light with the wrench next to it stays on for 20-53 seconds after starting the vehicle then it goes off. Is it urgent to get this checked or can I wait a few days? It just began doing this yesterday.

I replaced fuel pump fuel injectors distributor & major tune up& map sensor i noticed air intake hose was missing u can hear the vacuum sound i replace the hose in my van it ran for a cpl hrs & wouldnt start back up i dont no whats causing this problem! It would still stall out cut off after the repairs it still gave me problems when i press the gas it would cut off or back fire & lose pressure no check engine lights on or nothing
