Global Parts 1712203 HVAC Thermistor

HVAC Thermistor for Toyota and Lexus

Global Parts 1712203 is an HVAC thermistor used in vehicle climate control systems to send temperature feedback to the engine management system. On modern vehicles, the ECM uses this signal to manage A/C operation; on earlier applications, it can help shut the compressor off before damage occurs.

Compatible with select Toyota and Lexus models, including Corolla, Camry, RAV4, Avalon, Prius, Highlander, Sequoia, Sienna, Tundra, and several Lexus ES, NX, and RX applications. This part cross-references Four Seasons 37325 for the same application.

• HVAC thermistor for climate control temperature feedback
• Supports ECM-controlled A/C operation on newer vehicles
• Used in compressor protection strategies on earlier systems
• Direct fit for select Toyota and Lexus HVAC applications
• Part number 1712203 for catalog and service matching

Detailed Product Information

Global Parts 1712203 is an HVAC thermistor built for temperature-sensing duties within the air conditioning system.
