I have already removed the screws behind the ash tray but the front panel
doesn't come off

thanks

 

Disconnect your climate control cables from your heater box. The climate
control assembly is attached to the panel you're trying to remove.

I don't see any clips in the picture. You won't be able to see them on
your car until you get the panel off.
