Replaced the washer fluid pumps on our Trailblazer. Front was leaking and rear wasn't working at all. Good thing they are right next to each other, though this somehow did not stop me from mistakenly installing them switched around at first. Found that the tubing for the rear had also popped out of a coupler too, which was a PITA to get to. But once I had access, just pushed it back into the coupler. I put a dab of silicon sealant on it to prevent from popping out again. All tested no leaks! 🤘😀
