This is for a friend on anouther board.............

Just recently, when I shift from 2WD into 4WD, the 4WD light on the dashboard flashes all during the time I am in 4WD. Can anyone advise me on what this may be caused by? I searched and saw a message that some contacts may be dirty, but it didn't say which contacts. I also saw a message indicating a module may be going bad. Any advice would be welcomed. My e-mail addess is howardhouk|removethispart|@comcast.net. Thanks!

contacts are in the TC and there is no
module in a zuke, as it's a hand and
the lever. that or a bad bulb in the cluster.

The front dif may not be "locking in" if you have shift-on-flly. To find out  drive in 4wd and get  light to blink then jack the front  of car up (one side will do). Then try to spin the  tire by hand if you can the front dif is "not locking in"

George is correct. The four wheel drive isn't locking in properly. There is a diaphram in the differential that is probably leaking vacuum. That vacuum is needed to engage the auto hubs.  I had the same problem on my 00 Grand Vitara.  I was lucky enough to have it happen during warranty, even though it was the last time I owned it bewcause after visiting the Dealer for problem 11 times in 8 months Suzuki bought it back from me and I bought an XL-7. Haven't had any problems since then.
