My Heater Core went out about a week ago. I'm gonna be replacing the Heater Core, Blower Motor and the A/C Compressor all together. My A/C compressor went out also a week b4 the Heater Core. So my question is.... Would it be wise to replace the Evaporator Core at the same time? I don't know if it is bad. Thanks.

 

I wouldn't change it if it was mine. The heater cores do spring leaks and compressors go out but it's rare for the evaporators to go out. Not that they don't, just rare. When the heater core is out, check to see if there's any crud on the evaporator fins.
