I have a 97 Chev Extended Cab 4x4, Z 71.
It has the Electric 4x4 engagement buttons on the Dash.
I purchased it new, and after about a year, I have and am having problems getting the 4wd to engage when I push the button. Sometimes the button lights flash and then settle back on 2wd. Sometimes the lights don't flash.

I have had it to the Dealer several times, coupla times they couldn't find anything wrong. Said it was working! Before I got home, I tried it in a parking lot and wouldn't work!

The last time they replaced the actuator, and wire harness. the same thing happened , on the way home I tried engaging it and it wouldn't work.

Cost of repair, $389.00 and the 4wd still won't engage!!!!!!!

By the way, I'm a Senior Citizen, avid Deer/Turkey hunter.
I do not abuse the truck, have used 4wd maybe a dozen times and the truck only has 139,000 miles.

Any help would be appreciated!!!!!

i see 2 problems mostly with these...the encoder motor....which they probably replaced,or the switch itself....there is also an update to correct some 4wd issues
