I have owned my 97 ES for about a year and a half. I have noticed that the heated seats never worked. When I push the buttons on the counsil the light comes on but no heat to the seats. Is this a common thing in early 2nd generation ES300s? Is there an easy fix? Thanks

Most of the '97 ES have a common problem with defective heated seats, and there is actually a released TSB (technical service bulletin) for this issue. TSB's are known technical issues or problems Lexus (or any auto brand) is aware of. You can browse through http://www.alldata.com , find all TSB's listed for your '97 ES, print the list out, bring the list to your dealership, and point out the TSB for the heated seats to the service dept. They should be more than happy to investigate and hopefully fix the problem for you at minimum or no charge. Hope this info helps out

I've owned 3 Lexus's and NOWHERE does it say anything about, "Seat heater doesn't work above 70 degree". In fact, by mistake, I turned on the heated seat switch on a hot summer day and they worked perfectly. The outside temperature was in the 90's.

Alan,
It won't indicate in your manual. I didn't know about this until I talk to one of the lexus engineer a couple months ago. The system is design diffrently on all lexus.

I can't speak for ALL Lexus models, but for my 99 GS, the seats work all year round. I accidentally had the heated seats on during the summer (over 90 degrees) and I felt my butt getting real sweaty even with the A/C blasting. I looked down and realized the heated seats were on.

Let's clear something up, shall we? I was wrong by stating outside temp will affect the operation of heater circuit. This is how the seater unit work. There is a temp sensor unit right on the seat heater. It will take the reading from the actual seat. If the temp is cold enough, your sensor will complete the circuit and your heater will be turn on. I don't know the exact temp and so as the Lexus engineer(Steve). Also when it's reaching a certain temp the unit will turn off by itself. There is a way to check the unit to see if it's working. I can get the pin of the connector and you should be able to trace it.
