rear windshield hose

[buicfrank]

Can someone tell me or where to obtain the routing of the rear windshield washer hose? From firewall to rear window. Have used compressed air to blow it out but still clogged. Thank you. Frank

Related question. 2003 Yukon XL. Past 2 years rear windshield hose has disconnected 4 times. Have had it "fixed" 3 times. Lasts till I have used it maybe 6 times. Told by one mechanic it is a "poor design". This is very frustrating, winter weather can cause inability to see out rear window and the wiper cannot clear without washer fluid. I do not have the ability to replace the line myself. Have any of you experienced this? What would be helpful to tell mechanic?Any suggestions will be appreciated.
