Q: 4hi intermittently won't engage.

asked by on

It is a electronic unit, with auto 4, 2, 4hi, 4 lo. Sometimes when I press the 4hi button the light comes on, it sounds like the actuator moves, but then the front wheels don't spin with the rear. 4lo works just fine, only the 4hi and auto 4 are the problem. It is an intermittent problem sometimes it is just fine.

My car has 180000 miles.
My car has an automatic transmission.
