CD Changer Repair
By miko on Jun 20, 2008
The CD Changer installed in the glove compartment of my car has ceased to function for several years already (it failed to recognize CDs in the 6 disc magazine). Today, after a few google searches, I found a discussion forum that has just the information I was looking for, a potential fix for the problem a lot of people have experienced in their Alpine CD changers. So, I decided to give it a try! For better or for worse.
First, I removed the changer from the glove compartment. That was a fairly easy task of unplugging 2 wiring connectors, since my changer wasn't properly secured to the glove compartment (missing mounting bracket/screws).
Now, with the changer sitting on my desk, remove the screws on the side of the changer as shown below.
Then, pop out the plastic clips to remove the front panel.
Then, remove the springs that suspends the internal casing for anti-vibration using a long nose plier.
Then, remove the 4 rubber bushings by hand, and open up the case as shown below.
Now, the actual repair/adjustment. On the lower left hand side of the picture below, you will see this worm/wheel drive gear. There was a small gap between them, causing the worm to not driving the gear, and therefore, failed to pick up the CD.
To adjust it, I first loosen the screw that's holding the gear in place, using one screw driver to push it closer to the worm gear, while using another screw driver to tighten the screw. I used my hand to rotate the worm a little bit to test out the operation.
Then, I reversed the steps and closed up the case and place the changer back into the car. It worked! Now, I can listen to CDs again :) All-in-all, it took about one hour of work, and saved myself about $300 of repair bill.
Now, if I can find a way to repair the power antenna in the other car... part of the antenna was broken , so radio reception was extremely poor... I have found some exploded views of the parts, and hopefully I can take it apart and be able to order just the required parts, to save me another $350 (or save me $600 if I let my friendly dealer do the honor).
