I've had windshield washer motors make noise like they are running but not pump washer fluid, a new motor/pump fixed the problem. So don't rule out the motor/pump, but should look for other problems first......
It appears there is one pump/motor for both front and rear, the lines connect on either side of the motor. It probably runs in reverse to pump to rear line and run forward to pump to the front line.... ....another strike for the pump/motor being bad despite making noise....
Like ZX81 described you see the bottom of the reservoir where the pump and its lines connect behind the driver side front wheel well liner, pull a bolt and plastic twist stud to be able to peel it back and see..... ....You'll be able to see the plastic pipe for the front run up the side of the reservoir, looking in from the top you can see the plastic pipe running along the driver side of the engine bay, up to the hinge on the hood....
You either have a Clog, a Leak or a bad Pump.....
Run the washer pump, more than a few seconds, check reservoir fluid level and if it went down, look for leaks/drips/puddles on the ground of washer fluid....
No change in fluid level, no signs of leaks it might be a clog or bad motor/pump...
Disconnect the hose at the nozzles, run the washers, see if washer fluid comes out of the hose ends, if it does, the nozzles might be clogged....
If no washer fluid comes out of the hoses, I'd disconnect the lins at the pump/motor and get someone to activate the washer and watch if fluid shots out of the ports.
In fact, now I remember, that is how I finally figured out how I had a bad motor/pump on my windshield washer on another vehicle, finally just disconnected the hose at the motor and had someone activate it, despite making normal motor noise, barely a dribble came out of the port.....
