Heated Seats

[user134924]

My GS300 driver seat heater is not working. I've replaced the switch but it seems as the heating unit is not working. Is this a replaceable unit or repairable? Or, do I need to get a new seat as the unit is "built in"

Thanks for your comments.

The seat heater elements are replaceable but quite expensive so you might want to follow the diagnostic procedure for the seat heater system before you start replacing stuff. There is probably a diagnostic procedure described in the repair manuals for your car since there is in mine. I think the diagnostic procedure is mainly testing voltage and continuity on connectors.

The repair manuals are sometimes available on eBay and they are certainly available from Lexus dealers. You could also subscribe to online Lexus techinfo for $10 for a 24 hour period and download what you need. The repair manuals on CD that are sometimes on eBay are likely downloaded information from techinfo.
