Detailed Description

The Standard RU633T HVAC blower motor resistor restores blower speed control in vehicles that use a resistor-based fan circuit. It is a direct replacement for select Nissan and INFINITI models, including 2002-2006 Nissan Altima with auto A/C, 2000-2004 Nissan Maxima with auto A/C, 2002-2007 Nissan X-Trail, 2000-2001 INFINITI I30, and 2002-2004 INFINITI I35. This part cross-references Standard Ignition RU-633 for the same application.

For buyers searching for a blower motor resistor for Nissan Maxima, Nissan Altima, or INFINITI I35 HVAC repair, RU633T provides the correct terminal layout and voltage specification for the listed vehicles. It is also a fitment match for 2005-2008 Nissan Maxima and 2002-2007 Nissan X-Trail.

Common Issues It May Solve

• Blower motor works only on certain fan speeds
• HVAC fan speed is stuck on one setting
• Intermittent cabin airflow from the vents
• No response from the blower motor speed control
• Failed resistor in an automatic A/C system

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle HVAC configuration before installation. This part uses a male 3-terminal layout and is intended for 12-volt systems. Confirm the vehicle is one of the listed fitments, especially when servicing a Nissan Altima, Nissan Maxima, or INFINITI I30/I35 with automatic air conditioning.
