Heat Sensitive

The customer's concern may occur during hot weather or after car has sat for a short time. In such cases you will want to check for a heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent.
CAUTION: Never heat components above 60°C (140°F).
If incident occurs while heating the unit, either replace or properly insulate the component.
