Heater, Air Electric (AEH): Installation: Installation

WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

When performing any repairs that involve contact with high voltage components or systems, the technician performing repairs on the vehicle must verify that the system remains powered down during high voltage repairs.

This must be done by removing the service disconnect.
The high voltage check out procedure must also be performed to ensure that the vehicle is properly powered down.
The technician must know the whereabouts of the service disconnect throughout the repair.
The technician must ensure that no one reconnects the service disconnect while service is being performed.
The technician must recheck that the service disconnect has not been reinstalled in cases where the vehicle was unattended.

NOTE:

If installing a new air electric heater (AEH), new foam seals which are available as a separate service part kit must be installed on the new AEH. If the seals are not installed, or are damaged, airflow from the blower motor will bypass the AEH resulting in poor heating performance and NVH concerns.
