The fuse is the 20 amp WIPER fuse, located in the fusebox under the driver side of the dash, farthest on the left, 2nd one up from the bottom.

Rear washer may have it's own reservoir . Can you hear a pump humming when you activate the washer? Look in the under flooor compartment

I just had the same problem. I have an '04 4Runner and my rear wiper, fluid wash, and defrost stopped working after it was recently serviced. If you had the battery cables disconnected recently here is the solution...Start the engine and lower the rear tailgate window all the way... close the rear window and then turn the engine off. Restart the engine and the wiper,wash, and defrost. should work again. It has something to do with the computer which needs to be rebooted. Good luck.

Hello and welcome. all these functions run off the liftgate module. the liftgate module is located in the rear hatch. also the replacement liftgate module has to be programmed with software for it to function correctly

Testimonial: "Wow, I have had it in the shop, and it took them $250.00 to come to the conclusion it was the lift gate module. With no repair."
