Hey Mr. Kilmer! Thanks for all the awesome DIY videos. I'm been watching your DIY's for a while now and am going to attempt my first invasive repair. I have a 2002 Lexus SC430 and I've got some A/C problems. I've gone to a local auto chain for a diagnostic check and they came back with the "Expansion Valve is stuck open." You wouldn't believe what they quoted for the part and 5.5 hours of labor to remove the dash ($1200+). Lexus was even worse! After hearing those numbers I felt like I just got punched right in the bread basket. I usually take really good care of my SC430. I'm the first and original owner and have had minimal maintenance over the years (only had to change the serpentine belt, alternator, and battery swaps) as I do lots of preventative maintenance as needed and when recommended.
In any case, I saw your Expansion Valve Replacement video on a Toyota Camry. Unfortunately, I can't find anything specific on the 2002 Lexus SC430 and so I'm coming to you for your expertise. Honestly, from the mixed things I've seen I can't even begin to tell if the expansion valve is located on the drivers side or passenger side behind the glove box (as in your video). I do not have access to service manuals, and any of the online diagrams aren't very specific. I'd like to get your opinion and how you think I should attack this repair?
Truth be told, I just graduated from medical school and am applying to be a surgeon, so these tight quarters are going to be a real test of my skill! I just hope not to lose any fingers while doing it! After all, who would trust a three digit surgeon?!?!. I've linked a few resources below, and hope to hear your thoughts. Thanks so much for your time and awesome videos!
