FRONT left Tweeter Not Working

2017 sr5 non JBL left door speaker is muffled, and Dashboard tweeter is not working no sound. I haven’t messed with any wiring just bought the truck and sound is centered. amp under seat is plugged in correctly. Fuses? Any suggestions?

 

Most likely a blown tweeter. It’s pretty easy to pull the door panel and check to see if harness is seated properly.

 

I should have been clearer but the door speaker is muffled and the tweeter in dashboard has no sound at all.

 

Are both dash corner speakers not working or just the left?

Maybe pop the cover off and see what happening there and if im not mistaken
the right and left dash speakers run off the center speaker.

Sometimes, if aftermarket speakers get installed, the shop will disconnect the dash corners.
They claim its not needed if you have 2 or 3 ways in the doors.

 

Welcome to the forum

The dash speakers run off the HU/radio, the door speakers run off the underseat amp.
As well, the doors are only lows and mids.

The center speaker is a Dual Voice Coil speaker, it has both left and right.
Does it produce sound with the balance all the way to the left?

Does the rear door speaker work normally?

Swapped speakers and looks like front left tweeter was dead. Ordered the DS18 replacements on Amazon. Hope they improve the sound! https://amzn.to/4d6pjKT
