'94 S10 with 140k 4.3 auto with push button, (electronic) 4 wheel engagement. The lights on the button illuminate and the vehicle will go into lo range, but the front axle does not engage in either hi or lo. I see many suggestions to replace the actuator in other questions. Does the actuator have anything to do with the hi/lo range? A local dealership gave 3 possible culprits: electric shift motor (actuator?), Encoder assembly and or the front axle lock switch. New, these items total just under $1000. Is there a way to bench test these componants? Are there other componants that could be responsible? I just purchased it from a dealer so I have no history on it. Thanks for your time and help.
have the same problem?
