Where is the air conditioning relay located in the Chevrolet Trax?

Snow Frank Chuangku air conditioning relay is inside the engine compartment fuse box. Method to locate the relay: Open the engine compartment of the Chevrolet Trax and locate the fuse box. Disconnect the positive terminal wire on the fuse box to open the fuse box cover. Then you can see the inside of the fuse box. Remove the wiring harness of the fuse box to take out the fuses. After removing the air conditioning fuse, you can see the relay. Relay fault detection method: The operation of the relay only indicates that its coil is energized, but whether the corresponding contacts it controls are effectively closed and conducting still needs to be tested. You can directly disconnect the wire connecting the cold pump to the relay contacts, use a meter to measure whether the relay contacts are conducting, or directly measure whether the voltage on this side of the contacts has been transferred.
As someone who often tinkers with cars, I've removed the Trax's AC relay several times. It's hidden inside the black box (fuse box) on the right side of the engine bay - there's a diagram on the back of the cover. Look for small square black components labeled R2 or R5, slightly larger than fuses. Remember to disconnect power! Last time I replaced it, I noticed the AC relay sits right next to the cooling fan relay - don't pull the wrong one. Before checking, confirm it's actually faulty by listening for a 'click' sound in the engine bay when turning on the AC - no sound usually means relay issues. Note that newer Trax models might have different relay locations, so better check the manual to confirm.
