On my 98 there is a 2 door cabinet on the bulkhead in front of the passenger seat held in with 4 screws. Pull the cabinet and the washer bulkhead fitting is adjacent the wiper motor. Driver side is accessed above the brake pedal....on that side mine only has carpeting part of the way up, then open behind the dash. once there, you may have to push aside some insulation to reveal the hose and nut on the fitting. Have someone hold the outside while you loosen the nut. Yours may be diferent and as stated is a 96. Mine is the no frills Allure so much of these kind issues are fairly easy to get to without removing panels, etc. Hope this helps and Good Luck!!
