Question about 2003 GMC Sierra 2500HD
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.

this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
Legend of Abbreviations. ABS Antilock brake system.TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module

FOUR-WHEEL DRIVE SYSTEM
(a) Four-wheel drive control
Use the four-wheel drive control lever and center
differential lock button to select the following transfer and
center differential modes.
The "H" and "L" position of the four-wheel drive control lever
provides either lock or unlock mode of the center differential
depending on the center differential lock button position.
Use the center differential lock system if your wheels get stuck
in a ditch, or when you are driving on a slippery or bumpy
surface. When the center differential is locked, the vehicle
stability control system is automatically turned off and the
center differential lock and "VSC OFF" indicator lights come on
because the function that controls engine performance
As soon as the center differential lock switch is turned
on, the "VSC OFF" indicator light comes on. After the
wheels are out of the ditch or off the slippery or bumpy
surface, turn the center differential lock switch off.
Make sure the center differential lock indicator light and
vehicle stability control system off indicator light turn
"H" (high speed position, center differential unlocked):
Lever at "H", center differential lock button left out
Use this for normal driving on all types of roads, from dry
hard-surfaced roads to wet, icy or snow-covered roads. This
position gives greater economy, quietest ride, least wear and
better vehicle control.
"H" (high speed position, center differential locked): Lever
at "H", center differential lock button pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center differential unlock
"N" (neutral position): Lever at "N"
No power is delivered to the wheels. The vehicle must be
"L" (low speed position, center differential unlocked):
Lever at "L", center differential lock button left out
Use this for maximum power and traction. Use this for climbing
or descending steep hills, off-road driving, and hard pulling in
sand or mud.
In this mode, the braking feeling that occurs when the wheels
are negotiating a sharp corner is further reduced than in the "L"
(low position, center differential locked) mode.
"L" (low speed position, center differential locked): Lever
at "L", center differential lock button pushed in
Use this for maximum power and traction. Use this for hard
pulling in situations the vehicle cannot negotiate even in the "L"
(low speed position, center differential unlocked) mode. Also,
using this mode when driving down steep off-road inclines will
help contribute to increased vehicle stability.
