Rear Glass Defogger Printed Heater Repair procedures
| • |
Wrap tin foil around
the end of the voltmeter test lead to prevent damaging the heater
line. Apply finger pressure on the tin foil, moving the tin foil
along the grid line to check for open circuits. |
|
| 1. |
Turn on the defogger switch and
use a voltmeter to measure the voltage of each heater line at the glass
center point. If a voltage of approximately 6V is indicated by the voltmeter,
the heater line of the rear window is considered satisfactory.
|
| 2. |
If a heater line is burned out
between the center point and (+) terminal, the voltmeter will indicate 12V.
|
| 3. |
If a heater line is burned out
between the center point and (-) terminal, the voltmeter will indicate 0V.
|
| 4. |
To check for open circuits, slowly
move the test lead in the direction that the open circuit seems to exist.
Try to find a point where a voltage is generated or changes to 0V. The point
where the voltage has changed is the open-circuit point.
|
| 5. |
Use an ohmmeter to measure the
resistance of each heater line between a terminal and the center of a grid
line, and between the same terminal and the center of one adjacent heater
line. The section with a broken heater line will have a resistance twice
that in other sections. In the affected section, move the test lead to a
position where the resistance sharply changes.

Repair Of Broken Heater Line
Prepare the following items :
| 5. |
Using a thin brush : Wipe the
glass adjacent to the broken heater line, clean with silicone remover and
attach the masking tape as shown. Shake the conductive paint container well,
and apply three coats with a brush at intervals of about 15 minutes apart.
Remove the tape and allow sufficient time for drying before applying power.
For a better finish, scrape away excess deposits with a knife after the
paint has completely dried. (Allow 24 hours).

Rear Glass Defogger Switch Repair procedures
| 1. |
The body electrocal system can
be quickly diagnosed failed parts with vehicle diagnostic system(GDS).
The diagnostic system(GDS) provides the following information.
| (1) |
Self diagnosis : Checking
the failure code (DTC) and display |
| (2) |
Current data : Checking
the system input/output data state |
| (3) |
Actuation test : Checking
the system operation condition |
| (4) |
Additional function :
Other controlling such as he system option and zero point |
|
| 2. |
Select the "Car Model" and the
system to be checked in order to check the vehicle with the tester. |
| 3. |
Select the "Smart Junction Box
(SJB)" to check the windshield deicer. |
| 4. |
Select the "Current Date" menu
to search the current state of the input/output data. The input/output
data for the sensors corresponding to the "Smart Junction Box(SJB)" can
be checked.
|
| 5. |
Select "Actuation Test", if you
want to check the Smart Junction Box (SJB) data operation forcefully.
|
| 1. |
Disconnect the negative (-) battery
terminal. |
| 2. |
Remove the heater and A/C controll
unit. (Refer to Heating, Ventilation, Air conditioning - "Heater & A/C
Control Unit (Dual)")
|
| 1. |
Install the heater and A/C control
unit. |
| 2. |
Connect the negative (-) battery
terminal. |
