So this morning I was trying to clean my rear windshield and since it was 5 in the morning it was dark out and I couldn't see if anything was coming out. I could hear the pump and see the rear wiper moving. So after 10-15 seconds the rear wiper stops and I try the front squirters and nothing. I don't even hear the pump anymore. I checked both the number 5 and 12 fuse and both look ok. I also pulled the rubber grommet in the rear and all wires look good. I don't know what else to look at. Any suggestions?
