I replaced mine. It really was know problem. The hardes part was work under the dash. I would say that I believe the old fuse box be replaced. I have found that when you pull the fuse box that they are rusted. What happen is when the power is pulled thru the fuse the connecters heat up and when you shut it down they cool and when this happen after several year this pulls moisture in and rust moves in.By replacing the fuse box, you can add extry fuses. so for me it's a win win. After working on three 65, i found the same problem on the fuse boxs.
