Well since I bought my blazer the rear windshield wiper fluid has not been working. Last night when I had the entire intake box out I saw the windshield pump and saw the wire not connected but sitting right there. Well I plug it in and thought that would fix it, but its still dead. Is there a fuse for this? If so which one?

 

Looking at the schematics, it doesn't look like there is a separate fuse for the rear washer motor. I would verify power at the motor when the switch inside is pressed. There are two fuses for the rear wiper itself. One for the switch and one for the motor. If the switch turns on the wiper, then there is power at the switch.

The fuses will be marked RR WPR in the interior fuse panel and RR W/W in the underhood fuse panel. But again, if your switch turns on the wiper, both of these fuses should be good.
