Hello. I have a 1999 vw gti. The rear windshield washer does not squirt fluid onto the window anymore. I removed the nipple where the fluid squirts out in case it was plugged and that didnt help. Next I verified that fluid is actually leaving the reservoir in the engine compartment. To do this I disconnected the tube that carries the fluid from the reservoir to the rear wiper mechanism and then trigger the squirting mechanism and got fluid to shoot out of the reservoir opening. So now I am confident that the problem lies in the tube that carries the fluid from the reservoir to the rear wiper mechanism. I can imagine replacing that tube is impossible and I'm wondering if I should take my car to a garage and have them try to blow out the clog with high pressure air? Is their any risk of causing any other damage by this approach? Any suggestion on the safety of using high pressure to clear the clog are welcome.
TIA. Guid.
