HWH jack wont extend, 94pt

[Gregory OConnor]

I was preping my bus for radiator removal/rodding and new compressor
cooling lines today and I jacked the jack. I attempted to lift the
back end using two 8x8 timbers under the jack pads to gain some
height for frame jacksstands. the drivers side timber abruptly rolled
a bit in the gravel so I decided to drop the bus and use wider blocks
under the pads. the jacks retracted and I was never able to get the
drive/rear jack to extend once again?

The 94 hwh control pad only allow you to choose a pair of jacks or
auto level ;Both front ;both back ;both left ;both right or auto
level. I tried every combination to extend Drive/rear jack, no luck.

I wonder if I Knocked a sensor loose on the jack or confused the hwh
computer?
