2021 Nissan Rogue Blower Motor Clicking Noise TSB

Symptoms

Owners of a 2021 Nissan Rogue may experience a distinct clicking noise emanating from the HVAC (heating, ventilation, and air conditioning) case while the blower motor is actively operating. This specific issue, identified by Nissan, is often accompanied by the presence of snow and/or ice found within the HVAC blower motor case itself.

This Nissan Rogue blower motor clicking symptom indicates that external elements are interfering with the blower's normal function, leading to the audible clicking sound. It's important to note the presence of snow or ice as a key diagnostic indicator for this particular problem.

Diagnosis / Trigger Conditions

Technicians are instructed to confirm two conditions to diagnose this issue: first, a clicking noise is heard coming from the HVAC case while the blower is operating, and second, snow and/or ice is found in the HVAC blower motor case. If both conditions are met, the vehicle falls under the scope of this technical service bulletin.

This condition is specifically linked to the design of the cowl top cover, which, under certain weather conditions, can allow snow and ice to enter the blower motor area. The TSB applies to 2021 Nissan Rogue (T33) models equipped with the PR25DD engine.

Repair Procedure Summary

To address the Nissan Rogue blower motor clicking issue caused by snow intrusion, the repair involves replacing the cowl top cover. This is not a repair of the blower motor itself, but rather a preventative measure to stop snow and ice from entering the HVAC system.

Technicians are directed to refer to the Electronic Service Manual (ESM) for the detailed procedure. The specific section is: BODY EXTERIOR, DOORS, ROOF & VEHICLE SECURITY > EXTERIOR > REMOVAL AND INSTALLATION > COWL TOP > Removal and Installation. Following the comprehensive ESM procedure is crucial for a successful repair.

Required Tools or Parts

The repair requires the replacement of the cowl top cover with an updated part. The specific part number depends on the vehicle's trim level:

• S, SV Grades: Cowl Top Cover, Part Number 66862-6RR0B
• SL, Platinum Grades: Cowl Top Cover, Part Number 66862-6RR2B

Only one of the specified cowl top covers is required for the repair.

Important Warnings for Owners

Nissan emphasizes that these bulletins are intended for use by qualified technicians and are not 'do-it-yourself' guides. Qualified technicians possess the necessary training, equipment, tools, safety instructions, and expertise to perform repairs properly and safely.

Owners should NOT assume that a described condition automatically applies to their specific vehicle. It is essential to consult with your Nissan dealer to have the vehicle properly diagnosed and to determine if this bulletin applies to your 2021 Nissan Rogue.

Owner Action

If your 2021 Nissan Rogue is exhibiting a Nissan Rogue blower motor clicking noise, especially in conditions where snow or ice might be present, you should schedule an appointment with an authorized Nissan dealership. The dealership service department will be able to diagnose the issue according to Technical Service Bulletin NTB22-023A and perform the necessary cowl top cover replacement.

This repair is typically covered under warranty if your vehicle meets the conditions outlined in the bulletin.
