Here's another ticking noise. I have an 05' LE Crew Cab 4X4. Sometimes when I turn the climate control fan on, it makes a loud ticking noise like the fan blades are hitting something. I'll immediately shut the fan off and turn it back on, the ticking is gone. Seems to only occur when the vehicle is first turned on, i.e. it's cold but it won't happen throughout the day. The fan blows enough air...no problems there. Anyone else having this problem??:cheers:
