I have 2004 class c with Bigfoot hydraulic levelers the right rear Jack will not retract. It will extend but not retract. Further, been toLtd to check reservoir for fluid. Do my jacks have reservoir on each or is there just one reservoir.
Most jack systems have just one reservoir. If it’s just one jack, I’d follow the hydraulic line from that jack and look for a leak or a line that has popped off. Also an easy way to find where your reservoir is hidden.
I had this problem during my delivery. Day one. They could not move the MH out of the shop. Mine has a reservoir for each jack. You will need to check your specific model.
The problem with mine turned out to be a poor ground connection inside the individual jack's control box. Thank God it happened before I drove it home. It took them several hours to find the problem and fix it.
