User question
where is the blower motor resistor 2011 renault master location
Artificial Intelligence Response
Direct answer to the question
- Location: Passenger side of the cabin, behind/under the glove box on the HVAC (heater/AC) housing, directly next to the blower motor.
- Access: Remove or lower the glove box or the lower under‑dash trim in the passenger footwell to see the resistor/module inserted into the blower housing.
Key points
- Inserted into the air duct for self‑cooling.
- Identified by a multi‑pin connector; held by a quarter‑turn lock or 2 Torx screws.
- Same layout on Master III (2010–2019; also Vauxhall/Opel Movano B, Nissan NV400).
Detailed problem analysis
- Platform: Your 2011 Renault Master is the Master III (Mk3). On this platform the blower motor and its speed controller (resistor pack for manual HVAC, transistor module for automatic climate) are mounted together on the HVAC box behind the glove box.
- Exact spot: Look up into the passenger footwell toward the center stack. The cylindrical blower motor is obvious; the resistor/module is a small rectangular unit that plugs into the blower housing wall so that its elements/heatsink sit in the airflow.
- Fastening styles:
- Manual HVAC (four fixed fan speeds): “Resistor pack” with thermal fuse, typically secured by two T20/T25 Torx screws.
- Automatic climate control: “Blower control module” (power transistor on a heatsink), often retained by a quarter‑turn/twist lock or Torx screws.
- LHD vs RHD: Regardless of steering position, access is from the passenger side.
Current information and trends
- Common field reports on Master III/Movano B/NV400 show consistent passenger‑side, glove‑box/under‑dash access with either screw‑in or twist‑lock retention. Many owners also report heat‑damaged connectors, prompting pigtail replacement along with the resistor/module.
Supporting explanations and details
- Why it’s there: The resistor or transistor must be cooled by the cabin airflow; integrating it into the duct keeps temperatures within limits.
- Visual cues:
- 4–6‑pin rectangular plug.
- Plastic body with exposed coil frame (resistor type) or an aluminum heatsink plate (transistor module).
- Typical symptoms pointing to this part:
- Works only on highest speed (manual HVAC) → blown thermal fuse/coil in resistor.
- No low/mid speeds, or erratic/always‑on fan (automatic climate) → failed transistor module.
Ethical and legal aspects
- Airbag proximity: The passenger airbag sits above; do not disturb airbag connectors or power circuits while working. Disconnect battery negative if you’ll unplug HVAC components near SRS wiring.
Practical guidelines
- Quick access procedure:
- Ignition off; disconnect battery negative (recommended).
- Open glove box; either squeeze side stops to lower it or remove a few Torx screws to take it out. On some trims, remove the small under‑glove‑box kick panel.
- Locate blower motor; follow the short harness to the resistor/module in the housing wall.
- Unplug connector (depress latch). Remove two Torx screws or twist counter‑clockwise to release; withdraw the unit.
- Best practices:
- Inspect the connector for heat damage; replace the pigtail if pins or plastic are burnt.
- If the old resistor failed, spin the blower by hand and check current draw—an aging/seized blower can overheat new resistors.
- Verify cabin filter is clear; restricted airflow elevates resistor temperature.
Potential challenges and how to overcome them
- Tight working space: Move passenger seat back; use a headlamp and short Torx driver.
- Stuck twist‑lock: Use a flat blade on the molded tabs to assist the quarter‑turn without prying on the housing.
- Melted connector: Obtain the correct repair pigtail; crimp and heat‑shrink each joint to avoid future resistance heating.
Possible disclaimers or additional notes
- Minor trim variations exist; some vans allow access without fully removing the glove box—only the lower panel needs to come off.
- If you have automatic climate, the part is a control module, not a simple resistor; match by part number.
Suggestions for further research
- Check your VIN in a parts catalog to confirm whether you have the resistor pack or transistor module.
- Review the HVAC wiring diagram for your exact trim to identify fuses/relays and test points.
- If issues persist after replacement, measure blower current at each speed and compare to spec.
Brief summary
- On a 2011 Renault Master (Mk3), the blower motor resistor/control module is on the passenger side, behind/under the glove box, inserted into the blower housing on the HVAC unit. Remove the glove box or lower panel to access; look for a multi‑pin module retained by a twist‑lock or two Torx screws.
