I get this continuous clicking noise whenever the fan is on. It doesn't matter if it's hot air, cool air, or if the AC is on. The sound comes from the passenger side. The clicking gets faster as I turn up the speed. It kind of sounds like a relay but I don't know. Maybe something is stuck or something. Anyone else have this problem? It's annoying the hell out of me.

 

It sounds like your fan is hitting something as it turns.

 

Better fix the problem whatever it is before it fries the motor on your fan. Otherwise you'll be in for the wonderful job of pulling stuff out to get to the rad fan framework to replace it.

 

Mine used to make a clickin noise when they turned on. ExpensiveHobby22 is correct. Mine were hitting the plastic fan shroud (SP) around the fans. All I had to do was losen the bolts holding the fan shroud(sp) on and readjust. problem solved. that is if yours is the same.
