cool bill.
im not even sure why i'm messing with them, since down here in south florida, with the heat, they stay open 99% of the time, but when it gets cooler, like this weekend, and they are open, it gets a little chilly in the cab when they're open. LOL.
i just hope im not missing something on the vent doors that will prevent me from hooking them back up.
thanks again, and take care.
