Seat Arosa Overheating Fan Issue

Overheating is a serious issue, so addressing it quickly is crucial. It sounds like you've already done some initial checks, which is good. The radiator fan not kicking in is a common culprit. When you say 'impaired,' do you mean the fan isn't spinning at all, or is it spinning intermittently or slower than usual? Also, have you checked the coolant level recently? A low coolant level can also cause overheating and might prevent the fan from activating. Think of it like a garden hose; if the water pressure is low (low coolant), the sprinkler (fan) won't work as effectively.

Thanks for the quick reply! By 'impaired' I mean the fan does not spin at all, regardless of the engine temperature. The coolant level is fine, I checked that first. Is there a relay or fuse that controls the fan motor? I'm wondering if that could be the problem before I start messing with the wiring.

Yes, there is likely a relay and a fuse dedicated to the radiator fan. Consulting your owner's manual or a wiring diagram specific to your Arosa model would pinpoint their exact location. However, given that the fan isn't spinning at all and you've already checked the coolant level, a defective cable or plug connection is highly probable. The issue may lie within the wiring harness leading to the fan motor. As a general recommendation, unless you're comfortable with electrical diagnostics, I'd suggest taking it to a qualified mechanic. Messing with the electrical system without proper knowledge can sometimes cause more problems than it solves. They can properly diagnose the issue with specialized tools and ensure the cooling system is functioning as intended.

Took it to a local garage, and they confirmed it was a faulty connection in the cooling system. They replaced the connector, and the electric fan is now working perfectly. Total cost was 95€.
