There is a noise eminating from under the passenger dash. It sounds a lot like the leaves in the blower problem. However I just dropped the blower and there are no leaves. I activated the blower when out and it turns quietly. After reinstalling, I discovered the noise is coming from another squarish part under the dash which is a/c/heat related, located just to the right of the console. It has a metal link coming out of it. I can feel vibration and hear it if the key is on -even if the climate control system is off. I can silence it temporarily by pressing on the round center of it. It is definitely the noisemaker. What is this part and is it difficult to replace? Any links to a fix? Thanks and I love this site - just discovered it and it is helping save a ton of $$!
