Thanks, I'll check that out....but I'm still thinking that the switch isn't working as it's very loose and there is no difference in sound or quality when I slide the lever from outside to inside air. Dave

I don't know the technical names for it but I'm talking about the sliding button that adjusts the recirculated air from inside to outside. It doesn't seem to make any difference whether I put it to inside or outside air. So, I'm wondering if it is electronic and might be a fuse or if it's a mechanical problem. Dave

Greetings, I'm hoping someone can give me some advise. I don't believe my adjustment from inside to outside air is working. Would that be a fuse or a vacume line? Any help would be appreciated. Thanks,
