I recently replaced the cat converter in my 2000 Dodge 1500 Ram truck. When I got the vehicle back from the shop, the radio, the power mirrors, the dome lights, the cargo light, and the seatbelt solenoids did not work. Can't convince the shop they did it. All fuses are good. I suspect one or more fusible links are blown, but can't find them. Can anybody offer any clues or have another thought?
