I went to my local Lexus dealership today to have this update installed and I'm not very happy about it.
I told the service advisor I just wanted the update installed and referenced the TSB. They were ready to do all of their diagnostic stuff...
Someone parked their LX next to my LX at the zoo yesterday and probably thought I wouldn’t care to notice. The OTM Cruiser sticker on the back gave it away.
All right, got back from testing without the fan on. Same conditions and ambient temps as yesterday...
-128° to 70° took 1:43 (28 seconds longer)
-55° to 58° around the neighborhood (4° to 5* hotter)
-60° after a two minute stop (4° hotter)...

A few months ago I called up my local Lexus dealer and found out who they sourced their glass...
