[Shotimes] RE: HEATER CORE

[Raymond Aikens]

I have to pull my dash for the third time. First time was heater core, 2nd
was dead blend door motor and now I have same problems again.

I have run distilled water / antifreeze, so I'm not getting the Autozone
core LEAKING ALREADY. The unit is staying in defrost on all settings.

Need suggestions on copper vs aluminum heater cores. 

Tired of the EATC blend door and punched in buttons. What am I in general
looking at to pull the parts from a car with manual controls?
