windshield washer doesnt work on 03 windstar

Hi everyone here's yet another posting concerning my 03 windstar that I purchased a short time ago.
First, I'd like to thank the people who have taken the time to respond to my queries. Your advice is appreciated and I will follow it to the letter.
My next issuet is with my windshield washer. Whenever I try to engage the front "squirters", the only thing I hear is a whiring sound but no liquid shoots out. The back works just fine so I guess its probably the front windshield motor that has burned out. I'm pretty sure this is a project that even my limited talents can handle. I need to know how I should go about tackling this issue from how much I should expect to spend to where I need to open, remove, and replace.
Any info is greatly appreciated and thankyou once again for your feedback!

Just in the passenger side of the engine compartment, very close to the power steering pump fluid tank,you can see a small hose ( front windshield washer hose); you can disconnect it at this point, and activate your winshield washer and see if fluid is coming. If yes, there is something disconnected between this joint and the nozzles (under the cowl vent panel) If so you will have to remove this panel to gain acces to the hoses connected to the 2 nozzles. You can make this easy test first.
