Attention 981 owners: do your engine compartment purge fans work?

Mine used to, but haven't in some time now. I've been trying to troubleshoot them. Both fans run on low and high speed when activated with a scan tool, and the engine compartment temp sensor is giving plausible readings. I drove it yesterday while monitoring the engine bay temp, and it was less than 130 when I turned the car off, so perhaps it only happens in warmer weather.
