I checked out the actuator in the beginning of the process plus the cable was free and obvious. Went in advance and lubed it up for good measure at the same time.
I have a 2003 chevy blazer and possess no generate towards the front axle. After i push the buttons the tccm clicks, the buttons gentle and keep lit it is possible to right here the motor on transfer scenario run (for a short time) and no electric power to front axle.
Hmmm, feels like you've got another technique there — appropriately, I can not enable you to any further more as I am able to only help with what I'm acquainted with.

So I grabed on to the 2 wheel button and gave somewhat tug and it poped ideal out from the dash.
