another 4wd question

[b-stick]

got a 1998 chevy s-10 zr-2 and the 4wd will not engage..

changed the actuator out and it it will engage and the disengage in the same motion..

ocasionally will lock into 4 lo while pressing 4 hi.

need some help or something.

[Towman]

is the switch working like it should?

[b-stick]

the 4wd light...

when you push the button 4hi and 4lo lights blink a few times and you can hear it engage and the disengage then it returns to 2wd

[Towman]

sounds like the trancase actuator. check all grounds first then make sure its plugged in tight.


was it doing this b4 the motor went out?

[b-stick]

same thing....

but ocassionally would gear down but not fully lock in.

[Towman]

sounds like the trancase actuator just my thoughts. will ask a friend in am and let ya know what he said he builds transmissions you met him.

Check that damn switch on the dash first. I had one in my old 2002 that would blink when you would hit it and the lights would go off all the way, no 4wd. Bought new push buttons for the dash and had 4wd again, $25 I do believe.

try unplugging the transfer case control module and then plug it back in, try engaging 4wd again (make sure your in neutral, coasting at 1-2 mph might help as well)

With my 93 it was and still is the transfer case control module.I unhook the battery for about a beer to clear codes,hook it back up and get to switch to 4X for about 10 times.
