Hi. I have a 1989 Suburban that usually lived in a garage most of its life and seldom saw bad weather. This led to the windshield washer system becoming inoperable. I can hear the motor and the wipers come on but no fluid. How tough is it to take that tank off and clean it and the lines? Think it would be possible to run warm/hot water through it and unclog it?

 

I'd replace the lines, if anything due to age.

 

Good thinking. Much appreciated.
