Sporadic Driver's Window problem

Problem: Driver's window went almost all the way down today (maybe 2" of glass left) when it suddenly stopped working. Passenger side remained working fine. After 5 minutes of driving, normal operation returned to the window, but I still couldn't get it to go all of the way down. Once attempting to go all the way down, it got stuck at the same mark. All operation ceased for ~5 mins again. Rinse and repeat.

Any ideas? Not sure if it would be a faulty/dying switch or loose connections. I had changed my door speakers roughly 2 months ago and thinking the magnet on the back is somehow the culprit.

Also, not sure if related, but the window started squeaking over the last 2 weeks of normal use.
