Rear Window washer?

[97x]

You guys are a great source of information for new guy no nothing's like me!

So my next dumb question. My new to me SAAB 9-7.
Front windshield washer works fine but rear washer and headlight washers do not work at all. Is there only one fluid reservoir? The one is full.

 

[Sparky]

Yes, there is just one, with multiple pumps in it.

One reservoir, check. Thanks, Sparky.
Now, what is my next step?
It seems the headlight washers are supposed to work every fourth windshield wash? But they don't at all.
and the rear window doesn't pump wash fluid at all.
What should I check next?

Thanks!

I'm not really sure on the headlight washers, how that works. I had a Trailblazer so not sure.

For the rear washer, see if you can hear the pump motor run when you hit the rear washer button. If not, put a test light or something on the plug to the motor to see if you get power to it when you push the button. If you do, then you probably just have a bad pump motor.

If the pump runs but you get no spray in the rear, check for any washer fluid coming out of the lift gate weep holes. There is a check valve in the line back there that sometimes comes apart and just results in the washer fluid spraying the inside of the gate instead of making it up to the rear glass sprayer.

For the headlight washers, most people pull the fuse or relay as this is a stupid way for this to run. Waste of washer fluid. Check the relay and fuse as well as the motor plug. The two motors on the front of the tank are for front and rear. The one on the side is for the headlights.

A quick way to check the motors, swap the plugs for the front and rear motors. Try the front and rear washers and see what happens.
