Seat Inca Defrost Issue

My 2002 Seat Inca, gasoline engine, with 160185 km on the clock, has a weird issue. The air distribution for the defrost function seems to be failing. I'm getting low heat output, and there's an error stored related to the defrost flap motor. I suspect a defective cable or plug connection. Has anyone dealt with this? Before I start ripping things apart, is there a common weak point I should check? I've already ruled out the heater core itself. I've checked the air circulation flaps.

Sounds familiar. I had a similar issue with my Inca. The windshield fogging was a nightmare, especially on cold mornings. Have you checked the blower motor resistor? Sometimes a faulty resistor can cause weird air distribution issues. It's like when you have a dimmer switch that's gone bad, and the light flickers.

Yes, I did have a stored error code too. Honestly, I didn't mess with it myself. I ended up taking it to a workshop. They found a loose connection behind the dashboard panel controlling the defrost flap. Saved me the headache of potentially breaking something else. Better safe than sorry, right?

Interesting. Where exactly is the blower motor resistor located? And did you experience a stored error code as well? I'm pulling my hair out trying to avoid tearing apart the entire dashboard panel unnecessarily.

Took the Inca to the workshop. It was a faulty connection to the defrost flap motor, just as suspected. 95€ later, the heater is blasting hot air where it should. Thanks for confirming my suspicions; saved me a lot of time.
