My windshield wiper fluid box is cracked, the dealer wants $250 for it. Does anyone have an extre or know where I can get one for a better price?

 

Check www.car-part.com
If they don't list it in their inventory call a bunch of local junk yards or something .. $250 is just outrageous. Also try www.onlinemazdaparts.com

If none of those work, it might not be a bad idea to log onto www.mazdas247.com and see if you can find someone with a crashed Protege that might be parting out.
