Thank you for this video. I am about to tackle my passenger side door speaker. I'm going in a lot more confident after watching this video

Thank you. I did this repair. It cost me nothing but time. 👍👍

Apparently this is a common problem with the 2014-2016 Toyota corolla's, reliable cars, but crapy paper speakers and aluminum wires. There should be a recall. Here in Canada I just took my car to visions and had new front speakers/tweeters installed. Took them 90 minutes. They sound is great, better than original speakers. Total cost for the speakers and install about 500$. happy with my decision.

Can clean or replace connector but will corrode again. Better to solder wires to speaker and insulate.

This is only a temporary fix. The real issue is that water leaks into the door panel and corrodes the speaker wire. It will happen again after this repair.
