Issue: 1

Date: 12 July 2010

SECTION: 417

Headlamp Condensation





AFFECTED VEHICLE RANGE

CONDITION SUMMARY:

Situation:

Condensation, mist, or water droplets may appear in the lower section of the headlamps. This may be caused by the cooling of the headlamp lens causing lowered dew point of internal lamp atmosphere subsequent localized misting.

Action:

In the event of a customer concern of the above, refer to the Inspection and Repair Procedures outlined below to confirm the issue and, if necessary, replace the affected headlamp(s) and adjust the headlamps.





PARTS

TOOLS:
Refer to Workshop Manual (GTR) for any required special tools





WARRANTY:
NOTE:
Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only. Always refer to DDW to obtain the latest repair time.

DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.

INSPECTION PROCEDURE

NOTE:
Under certain atmospheric conditions, condensation, misting, and fogging is acceptable at any level providing it does not grow to the point where water droplets form and run down the inside of the headlamp lens. Lamps which show misting or fogging will usually clear with no adverse effect when the headlamps are switched 'ON'.

1. Inspect the headlamps for condensation, misting, and fogging.





^ If only condensation, misting, and fogging are evident, release the vehicle. (Figure 1)





^ If water droplets have formed, proceed to REPLACE AFFECTED HEADLAMP(S) below. (Figure 2)
