Washer Nozzle Removal

Washer Nozzle Removal
My '87 928 S4 has clogged windshield washer nozzles. The nozzles are held in-place by rigid, hard plastic tabs and I've not been successful in apply enough pressure to free them from the hood. I am concerned about damaging the underside of the hood, which in-turn could show on the top of the hood.
Any ideas?

dont take them out of the hood,
instead disconnect the hose lines from the connection under the hood, just above the heater motor area
then use compressed air to blow into the jets the debris should come out ,
this may take a few tries .
NOTE there may also be one way valves in your system,
removal of the hoses from the washer may be necessary or removal of the valves may be necessary
Then make sure you have a clean washer tank,
and the metal collars on the fill tube and the tank inlet are removed.
Usually wax will clog the jets or rust from the metal collars is filling in the lines and then clogging the jets

Regarding removing the washer nozzles: it's actually quite easy, particularly after you examine a new one off the car. There is a bendable tab at the rear of the plastic nozzle. To remove a nozzle from its mounted position; place fingers on the front of the nozzle and push rearwards. Apply a little upwards pressing with the same fingers and they pop right out. Dont use any tools. The hose inlet tube angles 90degrees underneath it and you will have to maneuver the nozzle to completely free it and the attached hose from the hood opening.
A couple of points; yes, it could be one of the 1-way valves causing your problem. Decide if you want to continue with the dual circuit tubing that includes the intensive cleaning solution path. If not, that will save money and routing complexity; not that I'm advising you to rid the intensive cleaning capacity. Secondly; the nozzles are expensive; around $90 for the pair. I found the 1-way valves via google for not too much.
My advise: 1) decide if whether you want to keep the intensive cleaning circuit, 2) replace the hoses, 1-way valves, Ts and splices. See how it works. If no-go, then replacing the nozzle jets is the only remaining option.
