When your heater isn't working properly, there may be a few different things wrong. However, if the air coming out is only lukewarm and you see other issues like moisture on the inside of the windows and puddles of fluid on your passenger side floor, then the trouble may be with your heater core. In this case, you simply need a heater core replacement for Mercury Cougar, which you can get today with Same Day Store Pickup (in most cases) from AutoZone. Also, try our Loan-a-Tool Program to get the tools you need to complete the installation of your new heater core.
