I had an issue with my cd button not working. I was able to take the radio apart and clean the contacts on the switch. There is a cover that pops off the radio, Then there are 4 screws toward the front face to remove . There are some side tabs to release, then you can remove the front face. Once it's removed there are 4 screws on the back of the face plate to remove. Now it gets a little tricky, there are 2 plastic pins the hold the black backing in place. You'll need to carefully pry the black back off without damaging the circuit board underneath. Once the face is apart , there are silicone strips with carbon dots that make the connection to the circuit board. You need to clean those with a que tip and rubbing alcohol as well as the contact surface on the circuit board. Then put it back together in reverse order. Good luck
