      Hey there, my sport trac makes a weird noise during idle. About every 45 seconds to a minute it makes like a clicking sound (just once). The rpm's don't change, it just makes this noice and I don't know what it is.

      My old 96 Ranger I used to have would do the same thing but the idle would change and rev a little higher.

      I am not worried about it I just want to know what causes it and it this is normal.

      Thanks

      I hear it too. but i think its just the thermostat. because everytime i hear it the fan kicks on high and the temp drops.

      It's more than likely the air conditioning compressor.
      The compressor will run in every position except for off, face vents only, or floor vents only. Defrost, floor and face, a/c and everything will have the compressor cycling. Open the hood and watch for the clutch to cycle.

      That makes sense. I usually keep it on defrost/floor so it would be on. When you say clutch to cycle do you mean on the compressor itsalef?

      Thanks

      This site is freakin' awesome, I was just gonna post this question as I hear the compressor kick on when I don't expect it, will keep the setting on either just face or just floor when A/C isn't wanted....not sure why Ford would do that since it does have the A/C settings....
