Heating of back glass and rear-view mirrors - the general information, check of serviceability of functioning of components, regenerative repair of a thermoelectric heating element

The general information

 Heating of external rear-view mirrors joins simultaneously with heating of back glass of the car.


While translating the switch of heating back glasses/rear-view mirrors there is a short circuit on weight of the electromagnetic relay of a chain of giving of a food to corresponding thermoelectric heating elements. The display lamp of inclusion of heating is built usually in in the switch button, but can settle down and on an instrument guard. The heating system relay is in салонном the assembly block of safety locks/relays.

The working element of a heater of back glass represents a horizontal lattice from the current-carrying threads pasted on an internal surface has flown down.

Check

The heating switch

Check up serviceability of functioning of the switch of heating for what remove the control panel functioning of systems of heating/air conditioning. Disconnect electroconducting and check up correctness of distribution of conductivity between plugs of corresponding contact sockets from the back party of the panel in both positions of the switch (see table 28).

Tab. 28 Check of serviceability of a condition of the switch of heating back glasses/rear-view mirrors


Thermoelectric heating element of heating of back glass

Turn the ignition key in position ON and include heating of back glass.

In order to avoid damage токопроводных threads of a heating element wrap up probeы the voltmeter an aluminium foil.

 It is necessary to translate the voltmeter in a direct current mode (DC).


Press positive probe the voltmeter to the positive plug of a lattice of a heating element, negative probe press to the grounding plug. The device should register pressure of the battery, otherwise check up a condition of a safety lock, the switch and connecting electroconducting. If pressure in norm, however, a heater part does not work, pass to a following stage of check.

Measure pressure in the central part of each of lattice threads. The indication in 5 6 In testifies to serviceability of a condition of a thread. The zero indication speaks about breakage presence between the centre of a thread and an element positive side. Indication overestimate twice (10 12) occurs in the presence of breakage between the centre of a thread and an element negative side. Serially check up each of lattice threads.


In the absence of breakages connect negative probe to weight of the chassis and repeat check, - indications should not change, infringement of quality of grounding of a lattice otherwise takes place.

For breakage localisation press negative probe the voltmeter to the negative plug of a lattice of a heating element. Wrapped up by a foil positive probeом start to probe токопроводные lattice threads, moving from outside food givings to weight. In a point of breakage the instrument reading should fall from several volt to zero.

Regenerative repair

Integrity restoration токопроводных threads is made by means of special two-componental electrowire paste of type Dupont № 4817.

Before to start regenerative repair of a lattice of a working element switch off a heater and allow to an element to cool down within several minutes.
Slightly smooth out the damaged site of a thread felt, then carefully wipe its spirit.

Paste two strips of an adhesive tape along a site of a thread subject to restoration. Carefully get mixed up эпоксидную paste with a hardener (follow instructions applied in a set). Put the received structure on the damaged site (with a tipping over approximately in 20 mm on edges of the intact thread).


Definitive polymerisation компаунда occurs in 24 hours after which protective strips of an adhesive tape can be removed from glass.
