1996 volvo 869 anti freeze leak right front seat area

[grg02001]

i have anti freeze coming from under the front passenger seat on my 96 volvo 960 - how are the seats heated coil or anti-freeze?

What else could be the source? the heater core is bypassed at the moment - and i have the front passenger carpet out, that is why i say the antifreeze is coming from the back front - the rear carpet could be so soaked it is still draining out? the front carpet was a soaked sponge when i ripped it out. thanks.
