hey guys, i was on my way to work today when i started to hear this annoying ticking noise, i turned down my music and heat to hear it better and it stopped, so i put the fan speed up and the clicking gets louder and faster...could have something small fell into the fan and the blades are hitting the wire or is this a commun problem? if anyone could tell me how to fix this and the cost to replace it that would be apreciated, thx

Take the blower motor out and make sure nothing is in it. If that don't help, get a new blower motor.

pull out your blower motor it is only 3or4 screws and a connector. see if there is anything in there
