schitzo1978 Posted December 6, 2009 Share Posted December 6, 2009 Hi I jumped in the car and it was cold today (32f). I flicked the seat heaters all the way to 3 and by the end of my ten minute trip I noticed my bum wasn't toasty warm. Upon further investigation I noticed the little orange light that normally goes on when you turn on the heater/ventillator is not turning on when I switch it on to either cold or warm. Asides from an oil change (done at a Toyota dealership) and new 17 inch rims with winter tires ( as well as having the dealer program the new set of tire pressure sensors), nothing else has been done to the car. Oh yeah I did have the battery chNged in my key fob at the Lexus dealership. Could any of these things have caused the issue? The aux power in my arm rest is fine. Thanks in advance for the help. Schitzo. Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted December 6, 2009 Share Posted December 6, 2009 Check fuse number 13 (15 amp) in the fuse box in the "Driver’s side instrument panel" of your car's interior: "13 FR S/HTR LH 15 A Seat heaters and ventilators" Quote Link to comment Share on other sites More sharing options...

1990LS400 Posted December 6, 2009 Share Posted December 6, 2009 would it be visibly apparent if the fuse were pooched? "Pooched"? You might be able to see if the fuse has burned through without removing it. Most Lexus vehicles come with a fuse puller -- the one on my LS is stored in the fuse box in the engine compartment ... don't know about the ISx50.

1990LS400 Posted December 6, 2009 Share Posted December 6, 2009 Jeez! An ISx50 has two interior fuse boxes? There is 15 amp fuse in slot number 16 for the passenger side seat heater/ventilator in the "Passenger’s side instrument panel" fuse box.

schitzo1978 Posted December 6, 2009 Author Share Posted December 6, 2009 The beauty of warranties. I'd just let Lexus fix it... 2 things, are you saying that the drivers and passengers side each have their own fuse...each on their own side of the car ? and 2, i will take it in but could you direct me to where the fuse boxes are situated ? i pulled off the driver side panel (the part the is only exposed once you open the driver door, and clearly there is no fuse box there. I am looking for my manual, seems like the wife put it somewhere and she is out for the rest of the day, thanks again, schitz Quote Link to comment Share on other sites More sharing options...
bartkat Posted December 6, 2009 Share Posted December 6, 2009 The fuse access doors are in the kick panels near where your feet to, not in the doors. Quote Link to comment Share on other sites More sharing options...
schitzo1978 Posted December 7, 2009 Author Share Posted December 7, 2009 The fuse access doors are in the kick panels near where your feet to, not in the doors. thanks ended up finding that in the manual you posted. Any idea why there are two fuses for the same function. One is drivers side and the other passenger. It's way to friggin cold up here to noodle around outside. I'll take it into the dealership. Are fuses covered under warranty? I was under the impression that fuses would be excluded like brakes and bulbs and clutches etc. Thanks again to all for help schitz.

Fuses shouldn't be blowing unless there is some other problem. I think the seats are heated and cooled so maybe one fuse for the heaters and one for the fans. Just my guess. Or one for each seat.

SW03ES Posted December 7, 2009 Share Posted December 7, 2009 Absolutely it will be covered...just tell them the heater doesn't work and let them diagnose and fix it. Quote Link to comment Share on other sites More sharing options...
