Next project on Skadi is to address the complete lack of any AC. I am going to convert to R134a, flush, and recharge the system while crossing my fingers that I do not have any leaks. When I press the valve on the lines I get some flow of refrigerant (very low, but something).

Here are the parts: conversionkit (88840-33020), 2 o-rings (90099-14044), 1 o-ring (90099-14045) and I have attached the Toyota service bulletin.

I was planning to have my shop do the flush and refill. Anyone have tips or things to be careful of?
