Okay, I really need help with this as I live in wisconsin and I would really like to use a heater in this time of year! This just happened this morning. I own a 2007 Crossfire Roadster. Upon turning on the fan tk blow heat into the car, a VERY loud ticking noise takes over, only when I turn the fan on 1-5 settings. On some Reasearch I took off the panel on the passenger door, and exposed the filter and what appeared to be a spinning cylindrical something? I have a video I'll put up on what I saw. The heat still works, but it makes the awful ticking noise that takes over every thing in the car and is absolutely horrible. Another issue is that my windows will randomly inch down every few seconds, and I've noticed that the convertible top down and up button flashes red, but stops when the windows inch down. What could this be? Is it because of the cold weather? Or what? Please respond, I wish to get this fixed and not drive to work in the mornings with this. Thank you in advance for the replies!
