Having 4wd problems with 2002 GMC Sierra 4x4. Have the auto 4 wd, 4hi,
4lo, 2hi feature. When select auto 4 wd and/or 4hi the front wheels do
not engage. Soon there after the service 4wd light came on, not long
after that the indicator lights on the buttons went out. Took it to a
local dealer, he said he replaced the modulator and it was fine. Next
rainy day selected 4 hi and could spin the rear wheels with no apparent
engagement of front wheels. Not getting any service 4wd light yet but
4wd doesn't seem to be working properly. The last time I remember the
4wd working properly was before the front differential was repaired due
to a crunching sound coming from the front end when the truck was
give the guy another chance......
I mean.....he said he fixed it,
your posts are saying that you "don't think" it's fixed.
so.....I say let's find out for sure if it's fixed or not, and
let the dude that did the repairs do the finding for no charge.
or....we can "ass u me" that your thinking that it isn't
working, means that it isn't working and that in order to
get it working you need the work of another worker instead
of the worker that said that his work worked out and now
it didn't need anymore work........in which case , by all means
carry it to another dealer.....where...yer liable to get a bill.
hopefully yer question was answered to your expections....
