Fine Cracks or Crazing on Head Lamp Lens - keywords appearance cover crack crazing fade head headlamp lamp lens light

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may comment of fine cracks or crazing noticed on the headlamp lens. This may occur if the customer or dealer installs covers over the headlamp assemblies. These covers may not allow the headlamps to maintain proper temperature and will distort the OEM headlamp lens assembly.

General Motors DOES NOT recommend the use of aftermarket headlamp lens covers. If a customer chooses to install these covers, any distortion caused by the covers will be the responsibility of the customer and will not be covered under warranty.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
