Before taking the dash apart to check the switch, I would use a multimeter to check for voltage at the pump when you push the button. That way you could rule out electrical problems altogether. If there's no voltage, then start digging...
I've had the hoses and even squirters themselves get crusty and clogged up on a few cars. If there are no problems with the circuit, I'd check there. Chances are that in a car this old, the hoses aren't in good shape anyway. If the squirters themselves are crusty, you can just use a small wire or pin to unclog them.
