It's been blown for over a year now, I just haven't had a chance to replace it. It could be the cold though as keep_hope_alive mentioned though that's aggravating it as the weather changes every 5 minutes here in central Ohio. Hopefully here in the next week or two things will be warm enough for me to take a look at it. You all have given me some good info and places to start, I will report back with what I find. Thanks!!!
