is the carpet on the pass side floor wet?

 

What does this mean?

 

I've knoticed the floor in my Lesabre gets wet sometimes and the heat doesn't work. I always thought it was some other leak but is this the true corrilation?

Most likely your core is plugged with goooooo.

 

Need to back flush it and get the crap out of the core. Find out which way the coolant travels through your heater core. Remove both hoses on the engine side of the firewall. Put a garden hose up against the return side with just enough pressure to get the water flowing. Too much and you will blow your core in half. With the water backflowing until it runs clean, hook everything back up and you will have heat again. :wink:

theres 2 coolant hoses that go inside the car right behind the engine, those go to the heater core

 

the core itself is under your dash inside the car, and requires taking most the dash apart to replace
