I was changing the oil today and noticed the cluster of control cables for the throttle, mixture, prop had there green plastic outer cover melted off in places just a few inches foreward of the firewall. After a closer look for the source of heat, it appears that the outlet from the heat muffs were the culprit. I am in Florida and rarely use heat, so the heat is continuously bypassing at the firewall diverter valve and blowing on the cables.
Could I just block off the inlet air to the muffs in the summer or would the muffs get too hot without flow through them. I'm thinking it will be fine but thought I would ask for opinions first.
