How it is said to have ended
- says it did not fix it2
- result not stated9
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Exterior Lamp Condensation and Water Leaks Service Bulletin
1Fault
- Exterior lamps such as cornering, turn signal, backup, head or tail lamps may show very small water droplets, a fine mist or white fog (condensation) on the inside of the lens.
2Finding the cause
Possible causes
- Condensation occurs when the air inside the lamp assembly reaches the dew point through atmospheric changes.
- Non-OE lamps are most often presented as holding moisture or with inoperative bulbs from corroded electrical connections; they appear to be installed as part of a collision repair.
Steps to confirm (in the document’s order)
- Normal: the mist is located mainly in the lens corners near the vents and does not cover more than half the lens surface.
- Normal: the moisture clears when the vehicle is parked in a dry environment or driven with the lights on.
- Leak: water has accumulated in the bottom of the lamp assembly.
- Leak: the condition will not clear when the vehicle is parked in a dry environment or driven with the lights on.
3Correction
Repair
- A condition covering more than half the surface of the lamp lens indicates the need to service the lens or lamp assembly.
Caution
- Depending on the lamp and the atmospheric conditions, the time needed to clear the lamp may vary from 2 to 6 hours.
- If the normal conditions are noted, advise the customer that replacing the lamp assembly may not correct the condition.
- Moisture that "comes and goes" is considered a normal condition.
