  1. My 1995 LS400 is doing the exact same thing. I got a schematic from the library which showed that if the light comes on all the fuses involved are ok. On my 95 there is a red/yellow wire which supplies the voltage to the drivers seat heater. This wire is larger then the others arround it since it carries more current. I lifted my wood center console to get at the switches. There are a couple of good posts on how to do this with out hurting the wood. On mine I confirmed voltage when the switch is made, both at the switch and also at the connector under the seat. This would prove everything to the heater element is working. The last thing I did was measure the resistence at the red /yellow wire to ground. A heater element should have a measurable resistence if it is not burned out. In mine the resistence was infinite so the elements are burned out. The only last possibility which I did not have a way to check out was that the heaters typically have a built in thermostat to open the circuit if it gets too hot. I think this would be built into the seat heater element. So I am at the point of needing to peel the seat leather off to fix this or replace the heater elements and I am not quite ready for this job. Let me know if you find anything else, but in my case I am pretty sure that the elements are shot and that I would need to remove the leather to fix this. I also started looking for a heated seat cover to use in the winter. The ones I have seen so far are not very warm or comfortable, but this might solve my problem with out messing with the seat covers. Good luck.
  2. My 95 also has seat heater problems. Please post back if you find something when you get this appart. Sometimes I think I get some heat out of it, but usually it does not heat at all. This could be a bad connection. My green light come on which would indicate that the relays are pulling in. So it is either burned out elements or bad connections. Anything you find out would be helpfull. Thanks.
