Mine makes noise early in the morning. It sounds like something is trying to open and close. I rarely use my a/c or heater too.

How can you tell which side of the servo is being bad?

I'm having the same tapping problem on the passenger side, but only every now and then. Only thing is I had an a/c issue before i started to hear the tapping. i have a 98 with oem navi, when i turn on the a/c i hear everything turn on, but no air comes out. When i change the air positions i hear servos working as they should but still nothing comes out. Could this be a servo problem too? Forgive me if I'm getting off subject, i'm fairly new to this.

No the blower doesn't work when i turn on the a/c. i connected a 12V battery directly to the blower and it works fine. All the controls work fine too, everything changes the way it's supposed to, but there's still no air. I was told by one guy i should replace the blower motor control. any other ideas?

break out the meter and see if your getting power to the blower. obviously somewhere your not if u can connect direct power to it and it works. time to start chasing wires.... i hate doing that

actually i did check that and i'm gettin the 12V to the blower but it still doesnt work, only when direct power is applied. a mechanic said it's probably just a button or a swtich. the dealership said it was the blower motor control or resistor. i'm not sure whicih one to replace, i'm thinkin to just replace them all.
