Im thinking and the bottom left hand side of the engine bay. (Facing Car) I have a 1988 Celica ST, dont know if it differs from GT.
The tank that supplies fluid for the windshield also supplies fluid for the rear wiper. It is located in the engine compartment.
The rear window wiper fluid comes from the windshield wiper fluid tank in the engine compartment on a 2001 Ford Escape
This light indicates that the car is low on wiper fluid. To refill the wiper fluid resovuoir pop the hood and pour washer fluid in the clear tank. Note: not all cars have a wiper fluid warning light since not having any wiper fluid isn't a big deal.
The back wiper fluid is supplied by the windshield washer fluid tank in your engine compartment on the 2003 Ford Explorer ( 4 door )
in the gas tank
Located on the bottom of the washer fluid tank; front one is for windshield and back one is for rear window if equiped with a wiper.
The fill tank for the rear wiper fluid on a 2005 Z71 is actually the same tank as for the front windshield. If the rear washer is not working and the tank for the front is full, then there might be a problem with a fuse or a hole in the line.
IT IS LOCATED IN THE GAS TANK. THE TANK HAS TO BE DROPPED TO CHANGE IT.
Open your hood and find the windshield wiper fluid tank and drain it. The pump is located on the side of the fluid tank and is plugged in. Remove the plug and the pump output first. Pull the windshield washer fluid pump out of the tank and replace it with the new one. Hook the electric connection and the pump output and refill your fluid tank.
It will not hurt anything, There's more water and antifreeze then there is wiper fluid and it will mix right up with everything, Don't worry
The windshield wiper fluid motor is located under the windshield fluid tank. You must remove the right front wheel well cover (plastic) to expose the bottom of the tank. Remove the rubber line and the electrical connection and pull the pump out. Check the rubber o-ring to make sure that it didn't tear.
Mounted on top and inside fuel tank.
