Toyota RAV4>> Electric equipment>> Check and repair of a heater of back glass
The heater of back glass consists of a set of horizontally located conductors which have been raised dust on an internal surface of glass.
Insignificant ruptures of conductors can be restored without removal of back glass from the car.
Check of a heater of back glass make as follows:
For detection of a rupture of the conductor of a heater of back glass include ignition, and the switch of a heater of back glass.
Connect one щуп the voltmeter to positive contact of a heater, and the second to "mass" contact. If the voltmeter does not show tension, check the safety lock protecting an electric chain of a heater. If tension is brought to heater contacts, execute the following checks.

Fig. 15.44. Use щупа the voltmeter which has been wrapped up by a foil, for detection of a rupture of the conductor of a heater of back glass


Connect one щуп the voltmeter to "mass" of the car, and the second щуп wrap up a foil and move a foil on the heater conductor (see fig. 15.44 ).

Fig. 15.45. Use of the voltmeter for detection of the broken-off conductor of a heater of back glass


Connect щуп the voltmeter in the center of each conductor of a heater of back glass. If the voltmeter shows tension about 5,5 In, the conductor of a heater means is serviceable. If the voltmeter shows tension 0 in or 12 In, means, there is a rupture of the conductor of a heater (fig. 15.45) .

Fig. 15.46. Use of the voltmeter for detection of a place of a rupture of the conductor of a heater of back glass


For detection of a place of a rupture of the conductor of a heater connect one щуп the voltmeter to the positive plug of a heater, and the second щуп move on the heater conductor from the negative plug of a heater. The point in which the tension shown by the voltmeter, will fall from several volts to zero, will be is a place of a rupture of the conductor of a heater (fig. 15.46) .
Before repair of a heater include it for some minutes.
Repair of a heater of back glass make as follows:
Restore a gap, using a special repair kit.
Smooth out conductors from two parties from a rupture of the conductor and degrease them.
With sticky tape stick glass from two parties of the conductor in a place of its gap.
Prepare glutinous current-carrying structure from a repair kit.
Put glutinous current-carrying structure to the place of a gap and the intact areas of each conductor on distance of 18 mm.
Dry up glutinous current-carrying structure during 24 h then remove a sticky tape.
