I have a '04 Dodge Stratus SXT with about 97,000 miles on it.

This just started happening today but whenever I have my heater on, there is a clicking noise coming from the dash area. My heater still blows hot air.

Anyone know what this could be??

I have a 2004 stratus at just over 95,000 miles. Caution I had to have a heat sensor replaced on the passenger side of the engine. However, do to previous overheating, it is now getting a new engine. Bad noise is now coming from the engine like loose parts. This was probably caused from the internal waterpump. I suggest that you get that sensor checked before it overheats on you.
