Alternatively you can use the air can to unblock the jets. Insert the can's tube into the jet and spray a good amount of air into the nozzles.
Now check for function by pulling the washer lever
The jets should do their job now. If not, check the washer fluid tubes for blockage in the following steps.
Step 6: Open the bonnet
Release the bonnet with the lever in the car's interior.
Move the bonnet catch on the exterior for final release.
Lift the bonnet and secure it with the prop rod.
Step 7: Identity washer tubes
Locate the washer tube under the bonnet. Look for a conduct on the bonnet's underside that is connected to the jets. It will have a T valve where the single tube coming from the fluid reservoir branches off to serve the two jets on the bonnet.
Step 8: Clean the washer tubes with air
Disconnect the washer tube from the T-valve so you can clean the tubes leading up to the two jets.
Connect your air compressor and insert the nozzle into the tube. Apply air pressure to unblock the tube.
Now pull the T-valve off the washer jet stub and insert the nozzle directly into the washer stub from underneath. Apply air pressure and repeat this process on the other jet. Reconnect the tubes and the T-valve and then close the bonnet so you can monitor the jets.
Step 9: Operate the washer pump

Step 10: TOP TIP !
If the jets still don't deliver washer fluid you have to determine the fault by elimination process. You may have a broken pump. Listen for the pump's high pitched buzzing sound when pulling the lever. If you don't hear it, check the pump's fuse in the fuse box. If the fuse is broken, replace it. If the fuse is looking normal, replace the pump. Consult a qualified service technician.
Step 11: Adjust the jet angle
Your washer jets should work fine by now, but
they may be adjusted at a wrong angle, so that on the road cars behind you get showered and your own windscreen still stays grimy.
Use a needle to adjust the jet's angle and aim.
Insert the needle into the valve and rotate the jet into position.
This is usually a trial and error process until the water hits the windscreen at the required angle." Now pull the washer lever - and you will have a clean windscreen.
