Front vent won't crank down
I noticed the vent cover on the front of my '95 Excella won't crank all the way down. It's the type that has the big plastic cover inside with lights as well as a fan. The fan turns on when the handle is turned to open the vent, and it turns off when it's turned to close the vent. But the vent remains partially open and the handle just keeps on turning. The vent is the type that pops straight up on a scissor type mechanism rather than being hinged at one end. Is the opening/closing mechanism shot? Does anyone have any suggestions?
