Windshield washer hoses and return valve
When I got the car the washers worked, but tended to also leak when I used them. There would be a puddle of washer fluid under the car. A few months ago it stopped working. By that I mean the motor ran but all the fluid poured out underneath the car.
Before today I pulled the LF wheel and liner and verified that the motor was OK, and that the reservoir itself wasn't leaking. The leak seemed to be coming from under the cowl.
Today I got around to pulling the wiper arms and cowl off to see what was going on. The T connector was rotten and was broken. It also looks like it wasn't reassembled properly by Mr. Bumwrench, the PO's mechanic. Somebody has been under the cowl before me.
Here's what I see. A tube comes from the reservoir to a T connector. The T splits off to the LH rubber elbow which is attached to the nipple for the wiper hose. The RH of the T WAS plugged directly into the rubber elbow for the RH wiper nipple. But it had broken off and I assume that's where all the fluid was leaking from.
Question 1: Shouldn't there have been a piece of hose connecting the other side of the T to the RH rubber elbow? Instead of the T being plugged directly into the elbow.
Question 2: on the LH hose I note that there is a one-way return valve that seems to connect the hose to the rubber elbow. It also seems to greatly restrict the flow. It seems that one end fits into the rubber elbow and the washer hose fits onto the other end. How many of these one-way valves should the system have? The dealer-site drawings only show one, but should there also be one at the RH rubber elbow?
Edit: I pulled the tube connector out of the LH elbow and it is not the one-way valve I thought it was. So... where does this one-way valve go? And. both rubber elbows barely flow any air. Is this correct? Is there some kind of restrictor built into them?
TIA!
