I am behind all the covers and I see the damper. From you description, it appears to be doing what it is suppose to do, it freely flaps open and closed. From my initial question that the turbo cool light never goes out - it is suppose to after running for 8 hours, will this damper affect the turbo cool shutting off or is there more to it?
Well I will work the first issue and see if that clears up our freezing problem. I'll monitor the turbo cool a bit more after that and see if we can get it to clear. Thanks again for your assistance!
