2000 kia sportage light indicates its in 4wd when its in 2wd and tries to go in to 4wd and 2wd off and on


The actuator on the transfer case has a ground short. This is why the light is on. And it will try to shift back and forth, if you have the switch at 2wd.

I have a 97 blazer 4wd i repalced vaccum switch all vaccum lines and made sure actuator cable was good lights come on like im in 4wd but diff doesnt lock in and actuator not getting vaccum


The vacuum actuator should move by hand without vacuum applied. You should also be able to see it move if you have someone switch the transfer case into 4hi/lo from 2wd and then back again. There is a vacuum switch on top of the transfer case that locks vacuum once the encoder motor engages the transfer case to lock the front axle into position, and then releases the vacuum once the encoder switches back into 2wd mode allowing the front axle to decouple. If you aren't getting vacuum, first check your vacuum lines for leaks, then check for vacuum coming from the transfer case when it's in 2wd mode.

You maybe have a bad switch and it's activating the actuator when it's not supposed to. Try unplugging the actuator by the front diff. See if that makes a difference.

My 2001 silverado w/69,000 miles has no light indicating 2 or 4 h


THE TRANSFER CASE MOTOR IS NOT WORKING TO INGAGE 4 WHEEL DRIVE. CHECK WITH DOOR OPEN WHEN YOU PUSH 4 WHEEL SWITCH YOU SHOULD HEAR MOTOR INGAGE 4 WHEEL DRIVE. IF YOU HEAR MOTOR BUT STILL NO 4 WHEEL DRIVE THE GEAR ON MOTOR COULD BE DAMAGED. REPLACE TRANSFER CASE MOTOR.

1996 chev pu 1500 4wd acuator wired to stay on always.


Your best bet would be to take it to your local mechanic or yourself if you feel comfortable with it and first correctly rewire the actuator. If the chain still keeps slipping after this which it probably will you need a t-case rebuild.
