Please help!

Just rolled over my brother's 2003 Grand Cherokee in the snow. Half
over that is. Managed to get it back on its feet, but the wheels no
longer turn, in any gear (it's an automatic of course)

He needs to get back to the UK in 2 days...

I wondered if it could be a rollover sensor, and if there was a way of
resetting it.

Not much other damage, apart from a wing mirror, and no airbags went
off.

Please make my year and tell me there's an easy solution to the
problem.

Thanks,

Tim
