Hello, after my blower only went to defrost vents, I found out that having no vacuum defaults the blower to defrost only...so, for the time being, I wire tied the panel vents open via the panel actuator under the driver's dash...this has worked fine for the last few weeks, but the actuator fell off and now I only have floor venting..(even if I manually move the panel door myself, it no longer switches to panel). The door is moving normally through it's full range of motion, but nothing will switch to other vents now. Any ideas would be appreciated...thanks

*It's really getting hot in there now....has not one person experienced this issue out there?
