Checking the operation of the heated washer nozzles
When the ignition is turned on, the electric heating of the washer nozzles built into the hood begins. If you look at the wiring with the hood open, you can see the heater connector.
Sequence of work
1. Disconnect the plug and connect an ammeter between the connector terminals.
2. With the ignition on, measure the passing current, setting its measurement range to about 0.3 A. For normal heating of the injectors, the current should be approximately 0.1 A. The magnitude of this current is determined by the resistance of the heating coil, made of a special cold-conducting material.
3. Blow out clogged nozzles with compressed air. In most cases, this can be done with a car pump or a simple ball chamber. To purge the injectors, disconnect the washer fluid supply hose. If clogging occurs frequently, a suitable gasoline filter can be inserted into the fluid supply path to the injectors.
Installation of nozzles
Sequence of work
Pic. 3.14. Washer nozzle installation
The nozzles should be installed so that the holes are directed above the middle part of the glass (pic. 3.14), then even in the mode of intensive operation of the wiper, the glass washing will be effective. If the jets are directed too low, then in the mode of frequent operation of the cleaner, the liquid will not have time to wash the entire working surface of the glass.
Noise and creak of glass cleaner
The reason for the squeak of the glass cleaner is the discrepancy between the angle of the brush and the angle of the glass, so when working in one direction or another, the brush adheres to the surface in different ways. This shortcoming can be corrected by bending the lever. If this does not bring results, you need to contact a car repair shop, where using a special measuring tool they will determine the angle of inclination and set the cleaner brushes with a guarantee.
When installing the nozzles, use a pin or a thin paper clip. Carefully insert it into the nozzle nozzle and turn the nozzle to the desired angle.
