I have a high pitched whistle noise coming from my 1999 2.5L Jeep wrangler. Noise is heard mostly at idle.
The noise GOES AWAY when I take off the fan belt, so m not a vacuum leak. I have now replaced ALL of the components attached to the belt (alternator, water pump, pulleys, power steering, fan clutch) and the noise still persist. Its really driving me nuts that I can't figure out what it is. I would like any help.
Also, due to the colder weather coming in, i have noticed that the pitch of the tone increase when I put on the heater in the Jeep. I'm not sure if its connected to the heater or just because turning the heater on increases the RPMs slightly.
Could it be electrical? Here is a video, all suggestions are appreated; http://www.youtube.com/watch?v=BiG9syxz6…
