I have a 2005 galant with 90K miles.... My drivers side floor is soaked im talking like a puddle and the floor behind the drivers seat is soaked to???? And its December so all the water that was there froze!!!!! I can kinda see water in the floor panel next to my seat like around the trunk release and such...But i cant find where its coming from... Any help would be appreciated!!!!

 

ryan, i suspect you have a leaking heater hose, or buggered 'o-ring'

the diamante and galant share the same workshop manual which i downloaded from a US website, for $20.00 USD.

hope this helps, and may also sort your radio issues
