Stop in for a cup of coffee

I didnt have much to offer this morning. Went for brekkie, worst i have had in a long time. Then on to fix buddy’s truck, stuck in 4wd. New range sensor wasnt the problem. Pulled 4wd actuator and tried to get it to move. Scanner wouldnt actuate it.
I figured out the lock and rotate circuits, egernized it and it moves. Replaced it and calibrated it, oddly it now maybe works. 4 hours later.
