2003 Trailblazer, the windshield washer squirts out on passenger side but not the driver’s side.

The hose appears to be hooked up on the driver’s side but nothing comes out? What would cause this and how does one repair the problem. Thanks for your help!

 

If it is hooked up, then you might have a clog in the line or the spray nozzle, that's the only thing that I could think of.

 

I vote for a clog as well. You can try disconnecting the line to that nozzle and blowing air back through it to clear the clog. If you are gentle, you can try pushing a small wire down into the nozzle. If you were to try this, I would take a strand of copper wire from common electrical wiring. This shouldn't damage the nozzle, but still allow you to clear the clog. You might have to mess around with different wire sizes to get it cleared out properly. Start small.
