-
Attempt to operate each individual power window in
both directions from the master window control switch as well as from
each passenger door window control switch.
Did the jumper wire fuse open during the test?
Yes |
REFER to the Wiring Diagrams manual to identify the possible causes of the circuit short.
|
No |

corrosion (install new connector or terminals - clean module pins)
-
damaged or bent pins - install new terminals/pins as necessary
-
pushed-out pins - install new pins as necessary
-
Reconnect the HVAC
module connectors and all previously disconnected rear window defrost
system connectors and components. Make sure they seat and latch
correctly.
-
Operate the system and determine if the concern is still present.
Is the concern still present?
Yes |
CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a
TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB
instructions. If no Technical Service Bulletins (TSBs) address this
concern, INSTALL a new HVAC module. Refer to the appropriate section in
Group 412 for the procedure.

Component Test
Grid Wire Test
-
Using a bright lamp in the vehicle, inspect the grid
wire from the exterior. A broken grid wire will appear as a brown spot.
-
Run the engine at idle. Activate the rear window defrost switch. The indicator light should come on.
-
Working in the vehicle with a voltmeter, contact the
broad red-brown stripes of the rear glass window (positive lead to B+
side and the negative lead to ground side). The meter should read 10-13
volts. A lower voltage reading indicates a loose ground connection.
-
Contact a good ground point with the negative lead of the meter. The voltage reading should not change
-
With the negative lead of the meter grounded, touch each
grid line of the heated rear window glass at its midpoint with the
positive lead. A reading of approximately 6 volts indicates the line is
good. A reading of 0 volt indicates the line is broken between the
midpoint and the B+ side of the grid line. A reading of 12 volts
indicates the circuit is broken between the midpoint of the grid line
and ground.
-
Pinpointing the exact position of the break can be
accomplished (if the voltmeter reads 0 volt when the midpoint of the
grid line is touched with the positive lead of the voltmeter) by moving
the positive lead of the voltmeter toward the B+ side of the grid line
and touching the grid line until the voltmeter reads 12 volts. If the
voltmeter reads 12 volts when the midpoint of the grid line is touched
with the positive lead of the voltmeter, simply move the positive lead
of the voltmeter toward the ground connection of the grid line and touch
the grid line until the voltmeter reads 0 volt.
