Seat Toledo Air Distribution Problem

Whoa, that's a bummer! Low heat output is the worst, especially now. So, you're getting an error code pointing to the air distribution flap? That messes with temperature regulation. The air distribution flap directs airflow, so if it's stuck on defrost, you won't get much heat elsewhere. Before you dive in too deep, check the basics, even though you mentioned it: Is your coolant level good? A low coolant level can mimic heater core issues. Also, have you felt both heater hoses going into the heater core (under the dashboard)? They should both be hot when the engine is at operating temperature. If one's cold, you might have a blockage in the heater core itself. If that's not it, and you're sure it's the flap, tracing the wiring and connectors is your next best bet as you suggest. Check for corrosion or damage.

Thanks for the detailed response. Coolant level is good, and both heater hoses are hot, so the heater core seems to be working correctly. You mentioned tracing the wiring. Do you have any specific suggestions on where to start looking for potential wiring or connector issues related to the air distribution flap? Is there a common failure point in the ventilation system for Seat Toledo models?

Okay, since coolant and the heater core aren't the issue, it really does sound like that flap. Honestly, without specific diagrams for your Toledo's ventilation system, it's tough to pinpoint a common failure spot. But! Since it's often a pain to get to, the connector on the flap motor itself is a prime suspect. It's probably buried behind the dashboard panel somewhere, meaning you'll have to contort yourself into the footwell. The good news is 95 euro sounds like they know it is a loose cable; they just have to find it. If you are not savvy with dashboards I suggest you go to the workshop. Good luck!

Just wanted to close this out. It was a faulty connection, like we thought. The mechanic found a loose plug on the air distribution flap motor. They re-seated it, cleared the error, and it's all good now. Cost me 95€, just like they guessed. Thanks for the help; it kept me on track.
