I tried to search the forum but could not find posts with siimilar issue, actually there were a bunch of posts from people trying to sell washer pumps on eBay
Last year my washer pump stopped working for a day, then it started working again. Not sure if that is related at all.
When I pull the stalk, pump starts with uneven noise and low pressure, after few seconds pressure returns to almost normal but noise is uneven.
When I push the stalk (rear window). It does struggle with uneven noise. First the flow is low and I sometimes see some liquid flow from the front washer jets even though I am pushing the stalk back. Also sometimes the pump gets slow and does sound like it is dying and water flow gets slow also.
I tried to make a video of it, but then it started working nearly as good as normal so I have nothing to show for.
I removed/reinserted the plug to washer pump and also wiggled the fuse. No change.
I am guessing I need a new washer pump, Does anybody think it may be something else?
