Hi, has anyone ever experienced their in dash cd head unit that has the navigation screen making a noise as if there is a cd inside but actually the key is not in the ignition.



I was just sitting inside the H2 and suddenly I can hear a sound like a cd is spinning inside the head unit. I am confused, they key is not in the ignition, everything is off, how come there is a sound coming from the in dash factory head unit <img src='http://www.canadianhummerclub.com/forum ... #>/huh.gif' class='bbc_emoticon' alt='???' /> Can anyone help <img src='http://www.canadianhummerclub.com/forum ... #>/huh.gif' class='bbc_emoticon' alt='???' />

Nope not that one, but recently had the radio stay on with the key out even AFTER I had openned the door. Turns out it was the module on the front wiper control as it is tied directly into the ignition and, if it gets wet and corroded, then really weird things start happening. If other "things" start happening, that would be the first place I would look. Steve at Master Mechanics took the module out (located under the cowling attached to the wiper motor) and got rid of the corrosion, dried it up, siliconed the sh*t out of the plastic casing around the outside where it snaps back together and re-installed it...works perfect!!

I had the same problem on an old car, get a can of compressed air (for computers..) and blast it in the cd flap. just a couple of quick bursts the first time. dont turn it on for a few minutes.

The dust can form a contact inside the unit and "spin it" on.



If that fails, then your going to have to take it out <img src='http://www.canadianhummerclub.com/forum ... ngHead.gif' class='bbc_emoticon' alt=':banghead:' />



FYI, the same thing happens on the indicator arms as well <img src='http://www.canadianhummerclub.com/forum ... ght_on.gif' class='bbc_emoticon' alt=':right_on:' />
