Is there a reservoir for the rear window washer on a 2004 Chevy Tahoe? If so where do you refill it?
I believe there is only one reservoir for washer fluid. A long tube connects the main reservoir. You may have the end nozzle plugged up if it is not working. Try to remove it without breaking it and blow on it to clear any obstructions. Some people have used the air hose with more pressure to clear it out. Once the spray nozzle is removed, see if there is any fluid coming out the open hose when the washer application is turned on. If not, see if the hose is connected in the reservoir or if there is fluid leaking from the hose.
I agree with the answer above. Main reservoir for both front and back windows.
