Well I suspect the drain clogging issue finally hit me. Had some really bad rain the last couple of days and this morning found a puddle on the passenger seat floor.
Since it doesn't smell like antifreeze and I know the heater core is behind the radio anyway; and everything above the floor is dry...well I'm guessing that's a clogged drain.
I'm changing out my fenders anyway soon, so I guess that's when I'll get to the drain hole unclogging fun.
On a good note, I hope to put some pics up soon from a Buick show I went to over the weekend. Found a really nice T-type Hawk. I left the owner a note about us, but I haven't seen a new member yet.
