Hello everyone: I am looking for an initial answer for what is the cause of the heating/cooling system failure on my 2002 ML320. I get no air of any kind. No fans, defrost or even sound. Nothing at all. Thank you!

 

Ok first welcome to the forums. Second you are more likely to get a response to your heating and cooling question if you post it in the general forum for your model, ML 320. This is the Audio and Electronics sub forum, the place to go if you have an issue with or want to modify or upgrade your OEM audio visual nav system. Good luck.
