Check the pump - - should be located on the firewall behind the back of the engine - -also, make sure that the hoses haven't decayed or come loose.
That's the nice thing about Phoenix - - no rain! I took the wipers off when I painted the trough at the base of the windshield and never put `em back on !
Either your pump is shot which is on the windsheild wiper resevoir close to the master cylinder.
Or your wiper switch may be fryed.
First see if you have power and ground at the connector that goes into the pump in the resevoir. If you do its the pump. If you don't see if you have power commimg out of the switch. If you do your wires are corroded somewhere. If you don't the switch is toast. Hope this helps.
Many years ago, a friend of mine replaced his wiper pump on his '77 Vette by accessing it through the side vent on the driver side fender. The bottom of the reservoir is right at the vent. I don't recall how he got the old pump out, or new one installed, I just remember how he accessed it.
The windshield washer tank is located on the drivers side wheel well inside the left front fender. The washer pump is attached to the bottom of the tank. To remove it you must remove the 2 screws that attach it to the wheel well. The screws are accessible from inside the wheel well, once they are removed you can pull the tank out through the top of the fender well inside the engine compartment. First unplug it and then try cleaning up the pump and the contacts where the wire attachs to the pump. Reconnect it turn the key on and try the washers, if the motor still fails to operate then more than likely you have to replace the pump assembly. Also be sure to clean the holes in the washer nozzles with a straight pin to make sure they are not clogged. If this still doesn't do the trick then get a meter on the plug where it hooks up to the pump and make sure there is electrical current going to the motor. If there is no current then your problem is more than likey inside the car, probably the washer/wiper switch or a fuse perhaps. I would check these 2 things first before replacing the the pump.
