Alright, after the last question I asked I am almost reluctant to ask 
again - but I am truly stumped.

I have an 85' GL 7 passenger, manual, 1.9L with A/C. There has been a 
growing wet spot on the floor running from the middle of the front of 
the middle seat to about 3/4 of the way back along the sliding side door. I 
thought I had a leaking window or hole in the floor but this is not the 
case. I was working on running some new rear speaker wire - I pulled 
back the carpet to find it is not water soaking the carpet at all but 
what appears to be coolant. So my question is how the hell can this 
happen? and why?

It was such an unexpected discovery that I have no clue (as usual). The 
rear heater does not work and I have turned off the valve to it under 
the rear seat if that matters. So what gives?

Any advice is greatly appreciated.
