37640 Blower Motor for NISSAN

37640 Automotive Blower Motor Overview

Use 37640 as the initial catalogue reference for the pictured cabin blower motor, then confirm the physical interfaces.

For catalogue item 6205-122, Cabin 37640 airflow depends on the 37640 motor, fan wheel, resistor or controller, wiring and an unobstructed filter working together. Use 6205-122 when comparing this 37640 airflow configuration.

OE Reference and Application

The primary catalogue number is 37640 . The recorded application is NISSAN. For 6205-122, Review the original connector photograph and fastening layout when catalogue applications include more than one HVAC configuration. Record 6205-122 with the approved OE reference.

HVAC Interface and 37640 installation

During work on 6205-122, Inspect the resistor or electronic controller and connector terminals if the original fault involved intermittent speed operation. Recheck 6205-122 before the lower trim is closed.

For item 6205-122, confirm that the 37640 centrifugal wheel clears its housing and that the 6205-122 connector lock engages without force. After seating 6205-122, test the available fan speeds and listen for rubbing, imbalance or intermittent electrical operation linked to 6205-122.

Frequently Asked Questions

How should item 6205-122 and blower number 37640 be verified?

Match 6205-122 to the complete 37640 marking, then compare the 6205-122 plug, terminal count, mounting flange and wheel dimensions with the removed NISSAN unit.

Can 6205-122 have more than one vehicle-side blower configuration?

Yes. NISSAN production changes can affect 6205-122; confirm steering position, climate-control specification and the original 6205-122 geometry before approval.

What circuit checks are useful when 6205-122 does not operate?

For 6205-122, inspect the fuse, relay, speed resistor or controller, wiring and ground before replacing the 6205-122 motor again.

Which details should accompany a wholesale request for 6205-122?

Provide item 6205-122, OE 37640, the stated application, quantity and destination; add 6205-122 carton or private-label requirements separately.

How can noise be avoided after fitting 6205-122?

Clear debris from the air inlet, check that the 6205-122 wheel turns freely, seat the 6205-122 flange evenly and keep wiring away from the impeller.

Request a quote for 6205-122: Send 37640, the 6205-122 application and required quantity for a fitment and supply review.

Electrical match: Confirm voltage, plug key and terminal count against the original motor

Motor interface: Compare flange contour, screw spacing and motor-body depth

Fan wheel check: Verify wheel diameter, height and rotation direction before ordering

HVAC function: Cabin airflow depends on the motor, fan wheel, resistor or controller, wiring and an unobstructed filter working together.

Installation guidance: Do not energize the unit while loose in the housing; secure it correctly before performing the functional check.

Fitment basis: Check voltage, rotation direction, cable exit and the position of every locating tab against the existing blower.

Quotation information: Provide the OE number, vehicle application, quantity and delivery country
