Hi, have 1999 fiat ducatto Riviera and missing handbook. Have been able to figure most things myself but would appreciate it if anyone could tell me what the 2 levers under the bench seats are for ..look as if they release something but not sure what. Also control panel lights show pump is on but not pumping water. Status lights on control panel do not come on and finally what is 12v socket on control panel for. Any advice will be appreciated, also willing to pay if anyone has relevant info and is able to scan it thanks
