Hello,

can anyone provide a wiring diagram for the heated seats on an 02 ES300? The harness is blanked out completely on the back of the dash piece for non-seat-heated cars, so a complete understanding of the wiring in that harness is needed. I will build a power supply and get aftermarket heating elements as well as a used climate control screen/buttons

My goal, of course, is to use stock buttons to control aftermarket heated seats in the complete absence of any wiring

thanks

I thought you all would get a kick out of this: I was an “elite” Lexus dealer today - in the top 5% most sophisticated dealers in the county (that’s a 15 year old fact) and guess what the parts manager and a service guy told me when I asked for the wiring diagram? THEY SAID “GO ON CLUB LEXUS!” I know they have access but they don’t want to help.

perhaps someone has it?!

I don't have a diagram for that model could always subscribe for a day here

Thanks for that! Good last resort but hoping for free. It is 16 years old, after all. Thanks again

Howdy. I stumbled across your post. I have a 2002 ES300 I am using as a commuter. I just replaced the HVAC panel because my LCD was mostly blank. I got a junk yard unit and it is working like a champ. My car does not have heated seats. I am curious what you ended up doing on your car? My non heated seat HVAC panel and the junk yard piece appear to have the wiring on the back of the panel. There are 3 plugs. The one closest to the passenger side has the wire plugged in to a dummy receptacle. So my question is do all the factory seats have the heated seat grids in them whether you have heated seats or not? If so it appears I have the wiring. If the seats have grids, I should just be able to swap in a HVAC panel with the heated seat buttons and I am in business? Thoughts or info? Thanks.
