• AC not cooling at idle – condenser fan not running

Frequently Asked Questions

Q: Are 6188-0129 and 6189-0165 a matched pair?
A: Yes. 6188-0129 is the male plug (harness side); 6189-0165 is the female socket (fan motor side). In the Yazaki 6188/6189 series, 6188 always denotes the male plug and 6189 always denotes the female socket.

Q: Can a bad fan connector cause AC failure?
A: Yes. On Toyota Corolla and Camry, the condenser fan shares the same harness as the radiator fan. A corroded 6188-0129 / 6189-0165 connector can prevent the condenser fan from running, causing AC to stop cooling at idle or low speed.

Q: What crimping tool is needed?
A: Use a ratchet crimper for 0.5mm² (18 AWG) Yazaki terminals – Hozan P-706 or Engineer PA-09.
