15. When installing the nozzle on early models, securely connect the hose to the nozzle and install the nozzle on the hood. Connect the electrical connector if necessary On later models, reinstall the nozzle and connect the hose (And) and electrical connector. Check the operation of the injector. If necessary, adjust the direction of the liquid jet from the nozzle (with a needle), one jet should strike slightly above the center of the area being cleaned on the windshield, and the other slightly below.
Headlight washer nozzles
16. Using a wooden or plastic bar, carefully remove the nozzle cover located under the headlight and remove the nozzle.

Washer/wiper control unit
21. The washer / wiper system is controlled by a central control unit (ZKE V). which is sometimes called the main block (GM V). This unit is located behind the glove box on the passenger side. To access the unit, remove the glove box (see chapter 11, paragraph 27).
22. Disconnect from the block sockets of electroconducting. Some connectors have locking levers and some connectors use sliding latches (pic. 17.22, a, b).
