have 92 4 runner 6 cly auto. wiper motor just replaced. now wipers will not work. at same time the rear wipers and rear window don't work, fuse OK. did notice at times if I slam the drivers door shut it all works??????? From the best I can understand the cause maybe a wiper relay. OK if so where the h,,l is it??????? I really do not wish to ripe all out to figure out. So if anyone knows where it is located thanks!!!! Spartin13

 

there is a relay on the driverside behind the cubby in the rear the plug may be loose but if it isn't it will have to be replaced.it controls all your rear window functions, including your wiper and defrost.good luck.
