Heating of back glass and rear-view mirrors - the general information, check of serviceability of functioning of components, recovery repair of a thermoelectric heating elementGeneral information
When transfer the switch of heating of back glass / rear-view mirrors there is a short circuit on the mass of the electromagnetic relay of a chain of giving of food to the corresponding thermoelectric heating elements. The indicator lamp of inclusion of heating is built usually in in the switch button, but can settle down and on an instrument guard. The relay of a heating system is in the saloon assembly block of safety locks/relay.
The working element of a heater of back glass represents a horizontal lattice from the conducting threads pasted on an internal surface of glass.
Check serviceability of functioning of the switch of heating for what remove the control panel functioning of systems of heating/air conditioning. Disconnect an electrical wiring and check correctness of distribution of conductivity between plugs of the corresponding contact sockets from the back party of the panel in both provisions of the switch (see table 28).
Tab. 28 Check of serviceability of a condition of the switch of heating of back glass / rear-view mirrors
Thermoelectric heating element of heating of back glass
Turn the ignition key in the situation ON and include heating of back glass.
Press the positive probe of the voltmeter to the positive plug of a lattice of a heating element, press the negative probe to the grounding plug. The device has to register battery tension, otherwise check a condition of a safety lock, the switch and a connecting electrical wiring. If tension in norm, however, part of the heater does not work, pass to the following stage of check.
In the absence of breaks connect the negative probe to the mass of the chassis and repeat check, - indications should not change, otherwise violation of quality of grounding of a lattice takes place.
For localization of break press the negative probe of the voltmeter to the negative plug of a lattice of a heating element. The positive probe which is wrapped up by a foil start probing conducting threads of a lattice, moving from giving of food to weight. In a break point instrument reading has to reduce from several volts to zero.
Restoration of integrity of conducting threads is made by means of special two-component electrowire paste like Dupont No. 4817.
Before starting recovery repair of a lattice of a working element switch off a heater and let's an element cool down within several minutes.
Slightly smooth out the damaged thread site felt, then carefully wipe it alcohol.
Final polymerization of a compound happens in 24 hours after which protective strips of an adhesive tape can be removed from glass.
