I have Big Foot hydralyc levelers that all of the sudden wont respond.

My guess is, one is not fully retracted from the last deployment.

Is it the automatic version of the Big Foot or does each operate independently?

It is automatic dashtouch panel and the left front retract light stays on but the mechanic got it to go out yet he has no idea ether
and Bigfoot wont reply.

Sorry, wish I could help. I thought that the Big Foot system had electric motors for each jack and maybe somehow you could get some juice to the one that is the problem, but with the automatic system, I don't have a clue how to do that. It really is pathetic that Big Foot won't return your calls.
