To get help, you might add if this coach is new or used, and what year. Also give the manufacturer of the jacks, as there are several manufacturers and the symptoms will be different.
One suggestion I have is to call the jack manufacturer and ask for their advice. I have found that whoever made the component will be usually happy to help with questions and problems over the phone.
Hope that helps...
