Part Time 4x4 Problem....Any ideas?

Hi -

I've had my car (2000 Suzuki Grand Vitara) for a couple of years now
and hardly ever use the 4x4 since it's part time and I rarely drive it
in the snow.  The times when I have used it in the snow, it totally
sucked!  I thought it was my bald tires, so I recently got new tires.
This winter when trying the 4x4 in the snow, my husband and I realized
the 4x4 appears to not work at all!  The 4x4 light has never come on
when engaged, and we always thought that was a burned out bulb.

Is it common for part-time 4x4 systems to fail?  We bought this car
used and suspect that maybe the original owner used the part-time 4x4
on dry pavement (which I understand is a no-no) so I am thinking she
may have wrecked it.

We are getting it looked at later this week, but I just want to get an
idea of how much it may cost to get fixed.  I suspect it may be
expensive.  Any ideas how much?  Of course, I am sure the cost of
repair could vary depending on the severity of the problem, but any
info I can have going in there would greatly help.

Thanks!

Could be anything from a fuse to a wrecked transfer case.
Assuming its push-button 4wd and not a manual lever:

-bad fuse
-bad connection
-bad 4x4 controller
-bad contact/sensor in transfer case/4wd actuator motor
-seized 4wd actuator motor
-broken transfer case
-missing front driveshaft/half-shafts....

the list could go anywhere.

If it looks to be a fairly expensive fix, make sure the entire 4x4
system is checked for problems, as it would really suck to put a
transfer case in it, and THEN find out it needs more, like a front
drive-shaft or front u-joints/half-shafts, whatever it may have. Or
maybe a front differential.

Thanks, Dave.  It has a manual lever - so I guess that means adding a
malfunctioning lever to the list.  Do 4x4 systems fail often?  I've
never heard of this happening to anyone else I know that has a
4x4....it's so surprising.

Also, regardless the reason it is failing, can you do any damage to
your vehicle if it goes unrepaired?

Hmmm, I was listing the best case, since there's more *cheap* stuff to
fail with the elect. system.

If you have the manual lever, I'm guessing either the linkage broke, or
there's something pricey broken or missing.

4x4 systems usually break with a fair amount of fanfare, so its not
really usual to have a stealth failure. If the transfer case has a
chain drive, perhaps that's what failed. But no, you'd still get the
4wd light.

So its reasonable to hold out hope its a linkage/engagement problem.

Just to check, does this thing have auto-locking hubs? If not, you need
to lock them manually. The 4wd light would light even if you forgot to
lock the hubs, though.
