Good afternoon, I need some help with repairing the heater core. I bought a new OE heater core and blower from Napa. The blower does work but I figured since I'm replacing the heater core I could replace the blower also. The reason why I'm replacing the heater core is because I noticed liquid on my front passages floor board. Could someone please give take time out of their day and give me a run down on how to repair both items. This is for a 65 Buick Skylark 2d.
