Headlights. Turn the headlight switch to turn the headlights, other exterior lights and instrument panel illumination on or off. When the lights are turned on, the lights-on indicator light in the instrument cluster turns on. To prevent discharging the battery, do not leave the lights on while the engine is off unless safety requires them.
Both headlight relays are inside the PJB, and not accessible unless you disassemble the PJB. I don't even know if they can be replaced they are likely soldered to the circuit board. If the highbeams also do not work then, you should check the 40A fuse in the fuse box under the hood (F4). He should be able to pop the others open, remove them, and then apply firm pressure to get the remaining rivets to release. Thanks ,the picture shows the rivet on the left and the plastic pop rivet on the right. It is odd that there is only the option to adjust the headlights vertically. Someone told me he aligned it.
Basically there are two screws/bolts on the back of each headlamp assem. The first is an uncovered 10mm bolt with a cupped, toothed washer. This one adjusts the entire headlamp assem up or down. Clockwise (tighten) for down. Counter-clockwise for up. The second is under a milky white plastic cap.
Put R2 where R1 was and see if the lights come on. Refit R1 to its original position and check again (sometimes removing the relay might clean the contacts and it starts working again). If the light does not come back on then we have determined that R1 is bad. Replace it. 2021 Mazda6 Touring; 2013 Mazda6 i Grand Touring; 2013 Nissan Note DIG-S.

It's not the temp it seems but how strongly the sun is hitting the sensor. So I've been out on 100+ days and not had the issue but got it on a 90 day. 48vi.
