I just finished a 3 hour drive and my wife was complaining the whole time about the floor being very hot.
when we got home i noticed the floor was extremely wet and hot. i pulled back the carpet and the underlay was soaked and steaming. it was almost too hot to touch.
I had the A/C on for most of the trip
does anyone have any idea what might be going wrong?
Thanks in advance.

 

you could probably have a hole in the heater core underneath the dash.

 

i thought it might have been the heater core but i wasn't sure if it would be that because i was only using A/C....
forgot to include in my original post...it's a 2000 4dr 4x4

 

What was the coolant temperature gauge showing?

 

it was about 115 celcius

 

im pretty sure it will keep flowing through the heater core even if you are using the a/c. i could be wrong.

 

Since that would be 239*F, I'm afraid the bad heater core diagnosis is correct. That's probably why the temperature is running high.

 

Thank you everyone for all your help, i will order the heater core tomorrow and rip apart my dash! i'm so excited *barf*
