A/C leak

Good afternoon,

That is the pressure relief valve for the compressor.

You need to replace the compressor.

The carpet inside my car on the passenger side front and back has a black liquid that smells sour, and when the AC is on and I make a left turn it makes a rubbing noise. What could it be?

Hi smlbhppy04,

This guide should help

There should not be any black liquids and if what you heard is sloshing noise as if water is moving around, then most probably the black liquid is contaminated water from the evaporator. Check for clogged drain hose at the bottom of evaporator housing.

my daughters mitsu.. leaks water into passenger side floor. Its not heater core its the ice buildup from the a/c. How can we correct it?

Hi there,

you will have to check & clean the evaporator drain tube,i think on these it will be at the lower portion of the fire wall behind the A/C unit it will be a short rubber tube.
