 (a) If the circuit breakers trip again:
 - replace the WHC-2 (2DG2).
 1 If the fault continues:
_
 - do a check for a short to ground at the wiring between the WHC 2 pin A/B and the circuit breaker (1DG2) and at the wiring between the WHC 2 pin B/G and the circuit breaker (4DG2).
 a If there is a short to ground:
_ - repair the related wiring.
 b If there is no short to ground:
_
 - replace the C/B-ANTI ICE/R/WSHLD (1DG2) and/or the C/B-ANTI ICE/WINDOWS/R (4DG2).
 (b) If the circuit breakers stay closed and the fault continues:
 - replace the WHC-2 (2DG2).
 C. Do the operational test given in Para. 3.

 B. If the test gives the maintenance message L SLIDING WINDOW SENSOR associated with ECAM message ANTI-ICE L WINDSHIELD, or ANTI-ICE L WINDOW:
 (1) If the WHC1 PN 6664287 is installed and if the ECAM warning is triggered on ground with OAT greater than 40 deg.C or if the cockpit window/windshield is directly heading to the sun and air conditioning packs off: - operate the air conditioning packs

 - after 5 minutes, open and close circuit breaker 5DG1 to do a reset of the WHC1.
 (a) If the fault continues:
 - refer to Para. C.

 (2) If the WHC1 PN 6664287 is not installed:

 - refer to Para. C.
 **ON A/C 215-220, 224-224,
 C. If the test gives the maintenance message L SLIDING WINDOW SENSOR:
 - disconnect the connector from the L sliding window (8DG1) and do a check of the resistance between pins A/C and A/D. (Ref. Fig. 202/TASK 30-42-00-991-007, 205/TASK 30-42-00-991-003)
