@vcheng : Not to my knowledge. Yesterday they did say I had good levels of refrigerant (don't think they had to put any in) but there was no mention of the drier cartridge replacement at all. Again, hoping this little relay replacement solves the problem, if not it may be back into the shop.
Update: Relay replacement worked like a charm, everything is back to normal. Hopefully this will save others some time, it's an easy cheap thing to try first and see if it solves the issue like it did for me.
Great thank you! Will replace and see if it solves the issue beacuse it happned againNot sure if you still need the info, but if someone is looking for it , its C/OPN one (#90987-02022), you need to replace it by part#90987-02028. There seems to be a bulletin regarding the same ref AC light Blinking and AC not working.......... - ClubLexus - Lexus Forum Discussion
Replaced with the updated part from Amazon $19. Will see if during summer it starts acting up.Not sure if you still need the info, but if someone is looking for it , its C/OPN one (#90987-02022), you need to replace it by part#90987-02028.

Finally we got some high temps in NE area, so my AC did the flashing light on me yesterday. Which means non of the things that I have tried so fat worked for me.Replaced with the updated part from Amazon $19. Will see if during summer it starts acting up.
Can you tell us which of the connections did you re-seat?As another poster noted, check your connections to the compressor. I was having the same issue. I replaced the MG CLT relay and was still blinking. I went thru the connections and pushed tighter and eureka, blinking light stopped and cool air blowing!
What did you you do to fix this issue? i have the exact same problem..Replaced the relay with a new one from Toyota and that did not fix the problem.
The codes that it is throwing are not in the book:
Flashing Rear Defrost light & Rear A/C light
A/C comes on for 3 seconds with a solid A/C light - blows cold - and then auto-shuts off with the a Flashing A/C Light
Do we have any Certified-employed by Toyota Mechanics that could point me in the right direction? When you start pricing A/C components your jaw will hit the ground!
