Push the windshield wiper lever forward to spray washer fluid on the rear window. The lever returns to its starting position when released.
The windshield washer reservoir is used for the windshield and the rear window. Check the fluid level in the reservoir if either washer is not working.
The washer fuse should have power (battery voltage) while the ignition switch is in the RUN position. Verify both sides of the fuse have power. If the rear wash functions them it's not the fuse.
The switch signals the Body Control Module (BCM). The BCM energizes the front washer relay.
Input to BCM from switch is BCM connector C1,24 PK. Output from BCM to relay is connector C4 15 OG.
You need to verify continuity from the the switch to the BCM and from the BCM to the relay.
Hey Barry, go to your local O'Reilly's, Autozone, or Advance Auto and tell them your issue and ask them for their recommendations..... they WILL help you and it will be much easier than listening and trying to understand what I (or anyone) says on here..
The rear wiper has its own pump motor. pull the hose from the wiper and have someone engage to see if there is a clog. do the same at the motor. if bo liquid comes out then its the pump. also check fluid level in reservoir as well as a possible secondary reservoir
on my chevy blazer there are 2 pumps in the front resivior one goes to the rear wiper and the other goes to the windshield if you have 2 pumps one might be bad. there could also be something plugged in the hose. on my blazer the upper pump goes to the rear wiper. hope this helps.
your rear wiper motor might be faulty,in the front i would check your fluid level-if it is full and you hear the pump running-check your washer lines to see if they are pinched-usually around where the hood closes
If it shoots from the pump without lines connected, then there has to be blockage somewhere. You mentioned you blew the lines out, did you blow directly back through nozzles themselves?
