    92 Chevy WT, started plowing, seemed ok then I noticed I lost traction. While trying to back up my driveway I noticed the front wheels were not turning, just rear spinning. After going through hell and sanding to get back up my driveway, playing with the lever in all positions it went back in while running in my driveway for a while but I couldn't take a chance of it going out again and getting stuck. I heard there is some kind of electronic switch on the tranny? This is 6 cylinder shift lever on the floor. The front wheels definately had traction back up in the driveway after sitting at idle a while while I took the plow off and definately would not work down on the street. Any ideas and most of all how much will this cost me to get fixed. Thanks.

    Sounds like you need a new actuator on the front axle, located on the passenger side. Prolly gonna run you 80-100 bucks or so and a half hour of your time.

    If that's all it is that isn't bad. The fact that it did eventually go in is a semi good sign I think. I couldn't take a chance of getting stuck again as the roads were so icy I almost didn't make it back into the driveway, nearly took out my mailbox by a half inch, watched it go by my window, and almost slid into a car on the street. Suks when the 4wd quits.

    Sounds like the actuator, my 1989 scottsdale used to eat one every other year.

    If I remember correct those original activators where vacuum operated and somewhere around then GM came out with an electric replacement. My '94 was done in '96 and it's still working. At the time it was a little over a $100 installed.

    I Had the same problem, just got fixed

    I had what sounds to be similar, ends up it wasn't the actuator but the sensor on the axle cost $158 to replace. Works fine now.

    good luck

    The "sensor" your speaking of would be the actuator.

    If your changing the actuator, make sure you update to the newer style like '98, its instant on instead of waiting for the coil to heat and engage, any good GM parts guy can give you the update kit , comes with a small new harness to splice in, you'll never regret it!!

    My '90 hasn't gone into 4x4 in months. Can we buy the parts at AutoZone or NAPA or similar? Do you have any links for a site to buy it from?

    You can buy the actuators in the aftermarket (NAPA AutoZone)if you just replacing the actuator with the same style, but to upgrade an older truck with the thermo linear actuator to the much faster full electric actuator you need to head to the GM dealer and purchase an additional wiring harness to make it work.

    P/n is 12376317 for the harness.

    If you want a genuine GM actuator too, the p/n for it is: 26060073

    skip thatelectric headache

    electric this n that = = more problems.GET a aftermarket cable design its like choke cable.push pull on off daa.check your back advertizers in some 4x4 Magazine. just my opinion....electric doors lock you out in the cold without a coathanger.electric windows get stuck in the down position when it 20 degrees,electric seats dont move and icant reach the brakes.electric YUK
