SOURCE: I lost my 4 wheel

Well, just got back from the dealership, $762.00 later the problem is supposedly fixed. We'll see. They replaced the actuator ($550.00 part only) They also said by replacing this there is the potential to short out the brain box that controls the 4wd system. I have a 2005 Yukon and this problem first occurred around 38K miles last winter. When I took it in then since it was intermittent they could not identify exactly what it was. This time it had been inop for 3-4 days. I went to the dealer this morning and pulled in the service drive and shut the veh off, I could not get it in until 1pm so I left and ran some errands. Well low and behold when I started it to leave the service drive it was working. After making several stops it was on and off every other time I started it. Oh an by the way it is not covered by the 100k powetrain warranty since it is an "electrical problem." BS in my book. When I left the dealership I asked the service advisor if this one would be good for another 38k miles, he said Yes, well i should f-ing hope so. My 99' yukon had the same type 4wd system and it last more than 158k and never had an issue with the 4wd. I guess factory workers get 35 bucks an hour, for a job a trained monkey could do, but there parts are sh-t. No bail out for GM in my book, with this kind a **** the deserve to go bankrupt. As you can tell I am highly upset about it. In researching this I have found numerous complaints for the same issue and there are several TSB's from GM regarding the issue, but no recall, just bend over and take it.

The  actuator on the front diff or transfer case is stuck or bad. This will send a signal back and turn on the service light. In 2003 I believe the actuator is on the front differential.

SOURCE: service 4 wheel drive light came on and truck will

I have seen lots of problems with the 4x4 motor/acuator at the transfer case. If possible take it off and replace it with a used one, because it is very expensive. From my experience working on cars and trucks for 15 years that is usually the problem....but to be certain, have someone with a scanner hook up and check the codes for that problem.

Service 4 wheel drive dash light keeps periodically coming on what should that be


Could be a bad sensor or selenoid for the 4 wheel drive unit. The gears lock in electrically with a selenoid and this may be what is causing the warning lite. There are so many sensors on cars nowdays the only true way to figure this out is to take it to a dealer and let them hook it up to their computers and download any warnings from there. they should be able to tell you excatlly what is causing the warning light. Hopefully it is just the sensor.

My 1999 Ford Expedition 4 wheel drive service light on the 4 wheel drive is on..saying "service 4 wheel drive"? what does this mean and is it harmful to use the 4 wheel drive with the light on?


Usally these warning lights come on for a reason.
I would have someone plug a OBD II reader in and retrieve the code.
The code should be able to tell you specific information on why the light is on.
Until you find out I would not us the 4 wheel drive function.

Service 4 wheel drive


The service 4 wheel drive light comes on because there's a problem. The biggest causes of this I've seen are a software glitch in the final drive control module which the dealer can fix by reprogramming and the other is usually the electric actuator on the front axle housing. The only light that comes on by a timer is the one that says, "perform service" in your overhead console or odometer.
