Hey y’all!
My washer fluid won’t spray and I’m having problems trouble shooting. There’s fluid in the res, I replaced the water pump, and the wipers themselves work perfectly. How should I go about potentially unclogging the lines or seeing if the problem is somewhere else? Thanks in advanced!

did the fluid freeze?

 

Maybe back a month ago but it’s been 90 degrees this week.

 

try activating the pump manually

 

Can you hear the pump running?

 

if you don't hear the pump...have someone activate the washers...unplug the electrical connector at the pump...one wire should have battery voltage...the other should show ground.
