Toyota Magnet Clutch Relay 90987-02028 OEM A/C Compressor Relay — Direct Fit, New

The Toyota Genuine Magnet Clutch Relay (part no. 90987-02028) is the OEM electrical relay that controls the A/C compressor clutch, providing reliable engagement and factory-fit performance for many Toyota and Scion models.

This genuine Toyota relay replaces the factory-installed unit to restore correct electrical control of the air-conditioning compressor clutch. Built to the manufacturer's specifications, it ensures proper timing and signal handling between the vehicle's climate control system and the compressor, reducing electrical faults and helping the A/C system engage smoothly.

Which vehicles are compatible with this magnet clutch relay?

This relay fits a wide range of Toyota and Scion vehicles from the early 2000s through the mid-2010s. Compatibility includes popular sedans, SUVs, trucks and hybrids — check your VIN or parts catalog to confirm fitment for your specific year and model.

• Common fits: 2003–2014 4Runner, 2005–2012 Avalon, 2002–2011 Camry (incl. 2007–2011 Hybrid)
• Also suits: Corolla, Camry Hybrid, Prius, RAV4, Highlander, Sequoia, Tacoma, Tundra and more

How does this relay affect my vehicle's A/C performance?

The relay acts as an electrical switch that tells the compressor clutch when to engage, based on signals from the climate control system. A worn or failing relay can cause intermittent clutch engagement or a complete loss of compressor activation, so replacing it can restore consistent A/C operation.

• Controls compressor clutch engagement for reliable cooling cycles
• Prevents electrical arcing and delays that cause intermittent A/C
• Factory-designed to match original timing and current ratings

What are the installation and product specifics I should know?

This relay is designed as a direct OEM replacement for simple, drop-in installation with no modifications required. It arrives new and ready to install; basic electrical knowledge or a mechanic can complete the swap quickly using factory wiring sockets.

• Manufacturer: Genuine Toyota — ensures OEM fit and finish
• Part number: 90987-02028, type: magnet clutch relay
• Condition: new, direct replacement for factory-installed relay

When should I replace the magnet clutch relay?

Replace the relay if the A/C compressor fails to engage, engagement is intermittent, or diagnosis points to electrical relay failure. Because relays endure heat and electrical stress, proactive replacement can avoid roadside breakdowns and restore reliable climate control.

• Signs: no compressor engagement, sporadic cooling, or blown A/C fuses
• Diagnostic tip: swap with identical relay or test with a multimeter
• Replacement is inexpensive compared to compressor repair or diagnostic labor

Who this is for: owners and technicians who need an exact Toyota OEM replacement to restore A/C compressor control in compatible Toyota and Scion models. If you want a factory-spec part with correct electrical characteristics and a simple install, this genuine magnet clutch relay matches the original equipment for performance and reliability.
