Front winshield washer doesn't work. Pump does not run.

Found the amplifier and the wires going to the pump show 17.5 ohms at that connector with the pump connected. Is that what you mean, or do I need to disconnect the pump and ohm the wires only to check for a short?

Awesome, but your second instinct is right, from the pump connector to the amp connector, with them both unplugged, sorry if i wasn't clear earlier.

I got an amplifier from Rock Auto and it still doesn't work. Do you know of a source for a wiring diagram? Local dealer and shops will not help DIY's. Next logical suspect would be the switch on the turn signal lever, but I hate to keep guessing. Thanks for your help. I have no 12v at the amplifier on the wires going to the pump.
