Hyundai H1 Overheating
Summary of the thread
A 2015 Hyundai H1 with a gasoline engine is experiencing overheating issues, suspected to be due to the electric fan not activating. The initial suspicion is a faulty cable or plug connection. After testing, it was confirmed that a corroded connector was the cause, which was resolved with a repair costing 95€.

Good point. How would you recommend I test the fan motor directly? Don't want to fry anything.

Proceed with caution, of course. Your H1's wiring diagram should indicate the voltage of the fan motor, likely 12V. Disconnect the fan motor at its connector and, using appropriately rated jumper cables connected to a known good 12V source (like the car battery), briefly apply power to the fan motor terminals. If it doesn't spin, or spins very slowly, the motor itself is likely faulty, and a workshop visit might be best for safe and efficient diagnosis.

Thanks for the advice. Turns out it WAS a corroded connector. 95€ at the shop and the H1 is back on the road. Appreciate the help!

Overheating is never fun! You've jumped straight to electrics, which is fair. Before condemning the fan motor completely, consider it like a tap that's partially turned off. Is the fan motor receiving power, but struggling to spin freely? A failing fan motor could draw excessive current, or is it completely dead? Have you tried directly powering the fan motor to see if it spins?
