A/C Evaporator and Heater Core Replacement - Lexus RX300

RX300 was not holding pressure and the problem was isolated to the evaporator core by smell and verified using an ac sniffer tool. The compressor oil odor was noticed after the AC was recharged. The evaporator required replacement.
This video will show in detail the steps involved in replacing the evaporator and heater core. This is a tedious job but I've done it before and took me around 8 hours. For first timers, probably 12 to 14 hours taking your time. The dash and cross member must be removed to get to the heater and evaporator core housing. The wiper motor cowling must be removed in the engine compartment to get access to the supply and return AC and heater core connections on the firewall.
