Sprinter slide topper issue
Hello all, 1st time poster, new member, 35 year camper. Just bought 2014 , Keystone sprinter, 311bhwb two rear cable slides. Installed one of two, Solera slide toppers; started with the smaller 8 ft. After installing it PROPERLY, the slideout will only retract and not extend. The rocker switch was swapped but that's not the problem. Could I have severed a wire with the mounting screws? Has anyone else had this issue? I want it to operate properly and not manual override. HELP!
