Default Air Con

Hello Everybody a long time since I posted any thing still having the same problem with the air con flaps shutting down after only a very short time. you can hear the motor still running but no air coming out. Has anyone got to the bottom of this yet can't seem to find the solution online at all?

Thanks

Have you used diagnostics yet? The approach to your problem seems simple: Use diagnostics to check the flap motors and any limit sensors are working correctly and if o.k look for a mechanical problem. The time you have spent searching the internet could have been spent getting diagnostics info back, then diving in to check the physical flap connection or look for any obstructions?

Is your air cold? I thought I had an issue with the flaps and dampers too but it turned out that the compressor was defective, and there was no cold air generated- the flaps seemed to close in response to the air temp....May be worth a look.

VW service garage could not diagnose it but an independent garage did !

Diagnostics in the hands of a good technician can do more than just spit out a fault code. You can read out temperatures and check the flap motors are working as they should. If you had no fault codes then I would suspect the system thinks it is behaving correctly and responding to temperatures as it should. Data on the compressor operation is also available in diagnostics for those that know what it means. It is more likely that an air con specialist would be more familiar with using diagnostics than a garage looking for an easy fix fault code?

Midician makes a good point, but I'm also wondering if the heater matrix is getting hot and giving out hot air? Additionaly, temperature sensors may have shifted and both will appear 'normal' and not produce faults. I also wonder if the flaps are automatically closed if the air temperature entering the cabin is below outside temperature (no heat) to stop screen fogging
