Tips for Goofy

[Wow Collector]

Recently, I bought a Goofy off of eBay, and so far, only his upper snout moves to the story, and his speaker is severely underpowered compared to my Mickey. 
I have a few questions involving these 2 problems with Goofy:
Is there any sources that show how to repair a Talking Goofy, and if not, do you have any experiences doing such?
Is Goofys speaker supposed to be this quiet, and if not, how can i Remedy this?
Is there a special animation cord needed for Mickey and Goofy? I have currently been using the cord for Teddy Ruxpin and Grubby.
Is there a way to clean out yellowing from my Goofys eyes without breaking him?

Please reply below with any answers to one or all questions, please.
Thank you very much!

1. How long have you been using this Goofy? His servo motors in the lower jaw might still be stiff from lack of use. It can often take up to a week to fully unstick a WOW character's jaw. Moving it carefully during the tape should help it adjust. If it is truly broken, you'll have to open his head up and see if it's a servo motor problem.
2. His speaker might be damaged. This can be checked by opening him up as well.
3. Any audio cord will work with the two, however a Teddy/Grubby one is fine.
5. Peroxide on a q-tip may help if you are extremely careful. Do not get it into the machinery and especially do not get it onto the pupils, as it will strip the paint.

Thank you for replying to my post. I really appreciate your response! However, I have found a new problem. Whilst trying to unscrew Goofy to examine his speaker, some of the screws head patten began to strip off of itself. This problem has been very prominent in my WOW toys as of recently, and I would like to find a way to bypass this situation. I will tell you when I have fixed this issue, but so far I will just wait and hope for the best.
