Complementary items & upgrade path Pairs well with the updated magnetic-clutch relay 90987-02028 (used by Toyota as a later-design remedy for A/C light flashing); consider inspecting the A/C MG CLT fuse and the compressor clutch coil while replacing the relay. If your vehicle already uses 90987-02028, order that reference; if your original is 90987-02022/156700-2470, this unit is the correct style to restore clutch engagement.
