Question about Cadillac Cars & Trucks
I've got a 99 Eldorado that I just bought for my girlfriend. I was trying to figure out why the wipers/spray wasn't working and discovered the 30amp fuse was blown. I replaced it twice with the car off and it blew both times. I disconnected the neg battery cable replaced fuse and as soon as I hooked the battery up the fuse blew again. I didn't think a bad motor or pump would do that. How do you localize the problem wire/equipment?

It's the wiring ,there is a dead short to ground ! Looking at a electrical distribution chart that shows if that is the only system powered by the fuse , then isolating the circuit . It's not the motor or the pump , wouldn't blow the fuse unless it was on . Looking at a wiring diagram I see that fuse feeds power to the wiper switch through the accessory relay located in the under hood relay center . The relay could be shorted inside .

start at the wiper motor harness and follow it back( even if wrapped up with other wires) you are simply goin to check carefully along harness and check it hasn't rubbed through and it's making contact with steel, with go through firewall at some point, that is a good spot for rubbing, but check it all carefully.
