Porter Overheating Electric Fan Issue

My 2002 Hyundai Porter with a diesel engine is overheating. I think the electric fan is bad, maybe a cable or plug issue. It has 113823 km. Has anyone seen electric motor problems affect temperature?

Summary of the thread

A 2002 Hyundai Porter with a diesel engine is experiencing overheating issues, suspected to be caused by a malfunctioning electric fan, possibly due to a cable or plug issue. Corrosion on the plug is noted, which could affect the fan's operation. A similar issue in another vehicle was resolved by addressing a faulty fan relay, suggesting that both the relay and the corroded connection should be checked. Seeking professional diagnosis is recommended to accurately identify and resolve the problem.

Overheating's never fun. Sounds like you're on the right track checking the fan and its wiring. I had a similar problem with my old Opel Vectra – turned out the fan relay was shot. Might be worth checking that too, although a dodgy connection is more likely. Any signs of corrosion on the plug?

There's some corrosion on the plug. What happened with your Vectra when the fan relay failed? Trying to see if the relay is the problem, or if the corrosion explains the fan issue.

When the relay went on my Vectra, the engine temp would creep up, especially in traffic, but the fan never kicked in. If you're seeing corrosion AND overheating, it's probably the connection. Electrical stuff can be a pain. A workshop could diagnose it properly.

Thanks for the advice. Given the complexity and my limited time, I'll go to a workshop for a diagnosis. They quoted about 95€, which seems fair. Your insights were helpful.
