I have a 2002 Trailblazer with windshield washer problem. The washer motor works, but no fluid is coming out. The problem first started with one of the nozzles spraying poorly. Now they don't work at all.

Just replacing parts isn't the way to find the problem , viewing wiring diagrams an testing the electrical circuit with a DVOM - digital volt ohmmeter is . There are no relays involved . Do yourself a favor an take it to a qualified repair shop before you buy more parts that are not needed .

Trash could be in pump not letting it pump or line at windshield is glogged,remove hose at pump and see if it drains and check all lines .

Usually the windshield washer fluid is blue, but you could be using green bug cleaner or some other variety,

I had a similar problem on a nozzle that was on my car this winter. I removed the nozzle and soaked it in hot water for a few seconds, reinstalled it, and it worked, even though it was freezing outside.

You could also soak it in -20 deg. F windshield wiper fluid, after removing the nozzle, and that should work as well.

Good luck on this repair.

check the washer pump with the hoses from the nozzles removed. if the washer fluid comes out the nozzles are plugged. if not the pump motor is at fault

Most likely a bad washer fluid pump.

the washer pipe will have blown appart.this happens if you opperate the rear washer when it is frozen.it will either be off in the tailgate usually when this happens there is water around the catch when you open the tailgate.or in the headlining in the left rear,have a feel and see if the headlining is wet.to avoid this reoccuring use a good screenwash with frost protection.

you know..i have a 2002 kia spectra and for the longest time i didn't have a washer cap on my windshield washer tube..i finaly found one in a junk yard and popped it on so i could have a windshield washer that actually works..and it still doesnt.

try the fuse first. then try sticking a pin into the washer jets. then try having the washer fluid pump/motor replace. if those are not the case, then you need a new switch to operate the pump motor. (a whole new control column)
