It's getting colder and colder in NY. For the past few weeks I have noticed this strange crackling noise every time I turn the heat on in the car. I also hear the same crackeling noise when I change the flow of the heat from feet to front and feet ect. Any1 else also noticed this prob also? if so has it been fixed?

 

Not to me yet, but I hope you get it fixed.

 

hear the same... but I dont worry too much.... cold weather always brings out strange noises in all cars!

 

Yea, I think it's just the plastic warming up. Gotten so I don't notice it much but I do think that your ears are in tune with what's happening.

 

Is the crackling near the surface of the plastic vents or does it sound more burried? I think what you might be hearing is the mode door and the air flow door adjusting itself as everything warms up and/or as you change between blower modes. It sounds like a crunching ticking sound. Turn off the ac and then go slowly between 60-90 degrees. You will hear the doors adjusting themselves for the temp. I too have heard this several times. It's normal. I hope this helps
