Hint: Use a descriptive title for your new message
If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

I have a 24' telluride and I've noticed that whenever I turn on the fan and set it to fan speeds of 1, 2, or 3 there is a noticeable humming/low-whirring sound and it gets louder/changes pitch with acceleration. It's not overly loud and not bothering me too much but I've never noticed it in any of my other cars before. Is this normal?
