Hey guys!
So, I have been dealing with what I thought was a leaking washer fluid tank since January. I would fill up the tank, and within several days it would be empty, with just a few uses. I haven't had time to investigate this annoying problem, so I basically went without washers until yesterday.
Finding myself with a little spare time, I disassembled the washer tank assembly. I unplugged the pumps from the tank, and they seemed fine, so I plugged the holes that the 2 pumps fit into, and filled the tank with water to find the leak. To my surprise, the tank was solid...no leaks. So, I began investigating.
I reassembled the pumps and the tank, and had my wife operate the front and rear washers while I observed. No leaks! I knew something was up, so I had my wife continue to operate the washers. Lo and behold, after a few seconds, the rear washer pump sprung a MIGHTY leak.
I disassembled it all again, and it seems the bottom housing of the rear pump, which snaps on and holds the impeller, had developed a critical crack in the body, and the o-ring that seals it to the pump motor was out of place.
I don't know if that part can be ordered separately (it's been a few years since I worked in GM Parts), and I didn't want to bother with finding out, so I decided to repair mine. Using some petroleum jelly, Gorilla Glue, and black electrical tape, I repaired the bottom housing of the washer pump. Now, we'll see how long it holds.
I'll bet that bottom housing cracked due to freezing over the winter. If any of you are experiencing a weird leak from the washer tank, this might be the culprit.
