I mounted a small switch to monitor the front shutter.
1 It goes thru an open- close- open at startup.
2 Shutter closes at 40mph and opens at 34mph.
3 Shutter opens at cruise speed when a/c is running, it will stay open for
2-3 minutes after turning a/c off, then close as usual.
4 So far no other strange or unusual results.
I wonder if it will close during cold startup and help engine warm up faster
during winter months.
