Have a 1999 Blazer with a rattling tape deck. I don't use it since i have cd player but the rattling drives me nuts and I have no idea to stop it. Is a separate component from the radio in the dash. Th tape deck is under the dash.

 

check to see if the plastic panels are not snapped at the bolt to the floor..mine did and i had to glue it to stop the rattle.

 

After about an hour and a few hundred swear words. i finally decided to just place 3 or 4 layers of black electrical tape across the top which worked. No more rattle. Thanks for the input.

 

I ended up removing my tape deck completely and made a custom tray insert for a better finished look. Took all of 15 min to remove the 4 nuts that hold down the console, flip it over and its 3 more nuts that hold the Tape player to the brackets. Slide it out and there ya go.

No more rattle and im happier then a pig in mud.

 

All threads should be instructive as possible.

FIX:

KLUGE:
Duct tape holds better
