4LO only - 4x4 lights flashing

[MaxWaxed]

Hi

A bit stuck here. Just picked up my 97 2 door Yukon a few days ago.

All was well drives likes new and was in 2hi mode.

Jumped in the truck today and its in 4lo mode only. All three trans options buttons are flashing. 4lo, 2hi and 4hi.

Ive looked at the fuses and all good. Everything works bar this.

Ive given the actuator a whack with a hammer.

Any ideas gurus?

Cheers

Bigger hammer! Unplug the actuator and plug back in.
