Fuse 22 seat heater question (2015 CX-9)

[HickoryBoy]

2015 CX-9
Engine compartment fuse box… Took fuse 22 out and put it in 20 to test the rear power accessory. It worked. But while it was out of 22 I checked the heated seats they WORKED, while the fuse was out. So obviously that’s not the fuse for the heated seats. But the manual and everything I find online says 22 is the heated seats. What gives?

When you say they worked, did the seat actually became hot or you mean the lights were ON on the button?

Oooh, good question... it's April in FL so it's 100 degrees outside. I did NOT allow the seats to get warm, I just saw the lights come on. I'll check that out. You're probably right.

cause from the wiring diagram there is a relay that is triggered from the AC unit and that relay is powered by the fuse 22 on the power side so the light will come on and it will trigger the relay but you won't have any power to the seat heater itself
