Your 4WD is currently not working. There has been some problems with late model GM trucks 4WD. Some are related to the pushbutton switch on the dash. My 02 silverado was warrantied by dealer because of a bad dash switch. This just happened to me. I was told to check the fuse first, if it wasn't blown it would be in the switch. Sure enough the fuse was blown...replaced and now working fine. same thing happened to my 03 silverado 2500hd. its the 4wd actuator switch. i think there is a bulletin on this.
check fuse behind instrument cluster panel- mine blew but I can tell if it in 4wd- so no biggy
It means that there is a malfunction in the 4wd system.
The 4WD Warning Light appears as the characters 4WD with an exclamation mark, and indicates a fault with your 4WD system. If it's blinking repeatedly, the system is completely disabled due to an overload.
that 4wd is engaged and working if it blinks there is a problem with the 4wd
you need to service your 4wd. It means that the computer that controls the 4wd has detected a problem and set a code. You will need to have the system checked with a scan tool.
A malfunction has been detected
Sounds as though you have a faulty gear box.
The transmission has set a code and you need to get it checked.
It means your screwed. Got a 2007 myself and can not figure it out.
Need to check are replace the 4x4 actuator in the FRONT differential.
My rpm light came on but not my check engine light so what does that mean when the rpm light is on
Most 4WD vehicles use automatically locking hubs. By engaging 4WD, a vacuum is formed in the front wheel hubs causing them to lock up into the front differential/transaxle so they can receive power through the transmission. If the seals are leaking, then the vacuum will not form and 4WD will not work. As for the light not working, I suspect that different models use the 4WD indicator light on the console to either identify when the front differential/transaxle is engaged or when the front wheels are actually engaged. Not having the light on when attempting to engage 4WD can either mean problems with the front locking hub mechanisms or the front differential.
my check engine light stays on and the o/d light blinks....what could this mean?
The 4wd is automatic in the 1992 Subaru Legacy Wagons. There is an empty fuse under the hood that has a cover that says FWD that can be used to disable the 4wd and force it to be in front wheel drive, but by default, there should not be a fuse in it. When there is a fuse in the FWD connector, the dashboard will have a warning light that says FWD, indicating that you do not have 4wd enguaged. If the light is not lit and you do not have 4wd then you have a transmission issue that will likey need the expertise of a transmission specialist. Check the transmission error codes (as opposed the the standard engine error codes.) They will likely help you pinpoint the problem.
check the alternator and battery.
The check gauges light means that one of the gauges is out of the safe range.
That means someone needs to check the 2 VSV's near the front axle. They are more then likely stuck and need to be taken apart and cleaned.
take it to the autozone they check the engine light for free
A flashing check engine light is an indication of a misfire.
The fuse, if not, then the switch, then the motor, but by then you will also need a test light and/or a DMM.
Does the light say check gauge or check engine?
No special button, just pull the smaller gearshift down, and you will see the "4WD" light on the dash. down position is high 4WD and down and over to the righ and up is Low 4WD.
4wd comes on automaticly
If the button activates the 4wd still, its just the light bulb, if it does not, the the button does not work, or, you may have a short.
