It's a 66 Chevy Impala 4 Door with A/C & Heat. I'm sure any chevy in 65 & 66 with A/C and Heat will have a similar setup. Has anyone ever delt with this? It's such a pain! I can't get it to come loose! I've taken out all the screws.
its been a long time sense i put a heater core in a 66 chevy. but i don't think it was nothing special about it. sounds like you don't have all the bolts out. where is the heater fan motor, behind the fender well or on the firewall? might be some bolts behind the fender well .
