All the speakers work and sound great but the left door speakers will cut in and out while I'm driving

 

Happens when listening to CD's? If so it's the ribbon cable between the CD changer and the Head unit. Over time the cable stops making good contact and you'll have issues with the sound. You can pull everything apart and re seat it. Google for the fix as I'm too lazy to search for your solution as well.

 

Here's a few similar reports.

If it's only the "ribbon connector" that has come loose, you're fortunate since the next fix is a H/U replacement.

Please let us know how you solve this. That helps us learn.

Thanks for posting.
