Condition
Cause

Some customers may have one or more of the following concerns:
1.
2.
3.
Drivers Headlight stuck on causing a battery draw
Drivers Headlamp / Turn Signal / High Beam inoperative or ickering
Accessory Illuminated Emblem is inoperative
The cause of these concerns could be water intrusion from GM Accessory
Illuminated Emblem, which connects inline with the Driver's Side Headlight.
Correction:
- If the GM Accessory Illuminated Emblem was disabled per the original version of this PI, then remove the
illuminated emblem and harness. Next, replace it with a new GM Accessory Illuminated Emblem kit which has
been redesigned, see parts section below for more info. Install all the components in the new emblem kit.
- If the vehicle is coming in for the rst time with this issue, then perform the following.
Inspect for water intrusion/corrosion in the following areas:
1. At the GM Accessory Illuminated Emblem Connection(1), shown below.
2. At the Drivers side headlight connector and the inline GM Accessory Illuminated Emblem Harness (2), shown
below.
3. - If water/corrosion is found, then perform all necessary repairs to the Headlamp connector on the Body
Harness and clean the Headlamp Assembly terminals. Then remove the illuminated emblem and harness and
replace it with a new GM Accessory Illuminated Emblem kit which has been redesigned, see parts section below
for more info. Install all the components in the new emblem kit.
Note: The Headlamp assembly is not currently known to be a source of the water intrusion.
4. - If NO water/corrosion is found at any of the connectors, then the source of the issue is not the GM Accessory
Illuminated Emblem and normal SI diagnostics will need to be followed.
