I have a bad audiovox AWM 524. How do I replace it?

Either the unit's motor is bad or the mechanical parts are dirty not allowing the unit to change CD's or load them.

Check with Crutchfield as if they have that type of equipment they might have that info. Otherwise check on Hi Fi Engine.

Part Number VQ776900. I got it online for 99 cents but other places can be up to 7-8.00 dollars. I removed 5 screws on the sides and rear of the case. Took case off. Press the open button and help the drawer open with your hand while the motor tries to. Then remove old belt with pliers or paper clip, etc.
I did not take anything apart on the inside to replace the belt. Push the belt into the player over the larger wheel and then I pulled the belt with a paper clip over the smaller drive wheel.

tune the radio to 89.1

Any decent repair shop should have a large supply of replacement belts. The Part number isn't necessary. Just take the old one in and get a new one just 2mm smaller than the original. Some repair shops won;t sell them because they don't want you repairing your own property but a decent shop should sell you one.

Optical pick up replacement required to rectify this problem

manufacture of make of cd changer but it would be cheaper to buy new cd changer i would think but worth you checking

Try a cleaning disc in it

You have a problem with the try control circuit. It could be the switch is leaking across itself. Could be a problem with the tray motor control IC, or the Microprocessor is not reseting the open tray line correctly, or theres a cam assembly inside the unit that tells the microprocessor where everything is by means of small micro/leaf type switches thats out of alighnment or broken. If its seven years old, you got more then it was designed for and I would'nt invest a dime or the time into the repair of this unit. Time to take a trip to the electronics store. Good luck
