the intermitten wipers on my car havent worked since i first got it. High and low speeds work no problem at all (the two upper positions). But when i move the wiper lever to the intermiten position the wipers will run as if i put them in the low speed position, and when i move the switch back to the off position, they will continue to wipe two more times then shut off. Any ideas what the problem could be?

Sounds like it thinks you're trying to wash the windshield.

Does it work properly when you pull the lever towards you, that is, it fires the w/s washer pump and sweeps the wipers?

yea, theh washer jets work fine. Will try and replace the relay, thanks for the help!

also, is it common for the washer jets to take a minute to actually start spraying water? It usually takes a a second or two from the time i pull on the lever.

There should be a check valve to keep the lines full of fluid. Pop the hood and look-see if it's working. If you can't tell, remove it and check it out - should be able to blow into one end, but not the other. Reinstall it with the end you can blow into toward the reservoir. Mine went bad. I replced it with one I got from a pet shop in aquarium supplies.

Ok, i fixed the wiper switch finnaly, just where can i find the check valve? Im sorry, i feel stupid asking this but as you all know im sure i am not very mechaincally inclined. Is it a blue piece that is attached to the end of one of the two tubes going into the washer fluid?

Yeah thats it.

U can usually clean them with soapy water and a toothbrush. Check (use a pen or something) the valve first by pushing the ball bearing forwards(direction of water flow) and rinse it if the ball is free. Then U should be able to blow through it (forwards again) easily.

If its frucked then any new car dealer dealer should sell them for about $2.00 and are called one-way valves or as you said check valves.

The P-cars have check valves built in up at the top end of the system, just under the spray nozzles. To my knowledge, there's only a strainer at the bottom end down in the tank. They're built into the tee and the L-shaped connectors:
