Is it receommended to change the expansion valve, heater core (and blower motor) when changing the evaporator core? Have the change the evaporator as there is a leak. Toyota Dealer wants 6-7 hrs labor (about $880) and $600 for just the evaporator (part #88501-48010). Same part on Amazon is $400. Not sure what other charges will be. No lexus dealership here.
Found the Denso evaporator on Amazon -
(Denso 476-0039 A/C Evaporator Core) for $206. Have to order it.
Got the accumulator/drier kit.
Ordering the expansion valve from Amazon too.
Should I get the heater core too and the blower motor (mechanic said if blower motor needs to be replaced there is no need to remove the dash).
Which parts are better for 2003 Lexus RX 300? The AC is not working for the past few years but its high time we need it now. Changed compressor as it was burnt when it first stopped working but that didn't fix it all. Shop said there may be some filings from the burnt compressor that entered the system and that may have caused the evaporator core to leak.
