sorry about the earlier post..I must of been in the dark ages
is there a fuse I should be looking for? and what is the location, also
the rear lower rear hatch won't open. not my car it is a friend and
What Shep said. More info needed, are the lights on the dash switch off?
Or are they on, but when you attempt the shift, does it just blink
continuously and then revert back to the position it started from?
If there are no lights on, you need to remove the "atc" fuse which
is located in the fuse box under the hood. Remove it for at least
one minute with ignition off, then re-install and see if the the system
If you have a solid light on in the 2hi position, and then it just
blinks when you attempt the shift to 4hi or auto4hi and returns
to the 2hi position, this is telling you that it's attempting the
shift but not all the parameters are being met. In that case, it
could be any number of things. It would need to be scanned
for codes and have the data stream checked to see what's
actually going on. There are also numerous software updates
for that particular vehicle/t/case in those years. Often the
reflash will fix many problems.
I am having the same problem with no lights at all on the switch
position. I have an 2002 TB LTZ. I have removed the "4WD" fuse from
under the rear seat and it looks fine. Any other ideas on what it could
be, besides the switch not functioning? The switch position lights do
not come on when the car is started either. It seems to me like if
there were a major problem with the transfer case I would be getting a
"service 4wd" dash indicator. The 4WD worked well a few weeks ago, but
is only 2wd now. Thanks. Kenny
Try removing the "atc" fuse in the fuse box under the hood. Leave
it out for 1 minute and then see what happens. If your 4x4 lights
come back on, you need a software reflash. Actually, in 2002, often
the atc module has to be replaced and then reflashed with the
