No fluid comes out of those two spickets on my hood 1992 300e, a fuse? I cannot hear the motor going for the fluid, just quite.

Have someone try the squirters while you put your hand on the windshield washer pump on the windshield washer reservoir. If not working maybe the pump.... or could be electricity to the pump.

If the pump is working but not pushing out fluid, try using a very small needle and carefully insert into the "spickets " on your hood. Also look inside the windshield washer reservoir for 1) Fluid! (Obvious) and 2) to see if it has a lot of crud in it. If so remove and clean thoroughly.

Check the hoses haven't just simply corroded,had it on a 416gti Rover.If they're shagged don't just cut them back replace them.
