windshield washer not working????

[elk_hunter]

Hi all,

 

 This just happend today,  Was driving to work and when to use the washer, and the whippers worked fine, but now fluid at all.  Thought the fluid was low, but is competely full.  Is there a fuse that could be burnt out that pumps the fluid?  

 

Thanks !!

 

oh, it's a 99 GMC ext cab.

I had the same problem the last 2 days - the temps have been in the single digits....

 

my guess is the washer fluid in the tube freezes, and it dont work....

 

whats the weather been like for you?

 

ive got a 2002 Z-71...

its been below zero here and mine hasnt frozen (but i am using some red stuff called deicer i think)

well saying freezing is putting it lightly here in central il.  the last week or so, has been in single digits.  and past 2 days has been in the negatives, with windchill in the -30 to -40 range.  

 

 But my truck is kept in a heated garage, so dont see how it could be frozen, I though that myself.....but its not outside so i dont know.

Can you hear the pump run when you push the button? You should be able to hear the pump motor. Just turn the ignition on without starting the truck and hit the button. If the pump doesn't run it could be a couple things, a bad switch, bad pump or a fuse. I'm not sure if the washer pump is on a dedicated fuse or not. You can use a test light to see if the pump is getting current or not. My switch went out on mine at 20k miles. They fixed it ok under warranty with no problems.

 

Hope this helps.

There is a fuse specifically for the winshield washer pump.  Open the electrical center on the drivers wheel well.  In the second row from the bottom on the left center there is a fuse W/W PMP.  (You'll see it in the diagram on the lid).  I'd check there first....
