We are fast approaching a time where we will not be able to replace most parts. And we are already at a time where people with insider information have disappeared. Before it is all gone, this is a request for people with know-how to document their knowledge. For example, does anyone have a work around when a blower control module fails? Has anyone accomplished a manual work around when the electrical component of the Blend door Actuator fails? Has anyone been able to revive the large relays in the CCRM with a work around using other relays? And the list goes on and on. Although depleted from its prime, there is still a lot of know how out there that is not universally known. This section has a wealth of information already, but we are at the point where we have to become inventors to keep things operating. So if anyone knows some little trick that has helped them out in the past, this is the place to talk about it.
