I have a 2003 Buick Le Sabre LE and have a unserviceable heated seat on the driver’s side. The dealer has analyzed it no results said they needed to remove the seat for further checks. Where do you think the likely problem is and where I might look myself?
You probably have a bad heater element in either the seat bottom or backrest, that is what normally goes bad on them. Sometimes they both go bad at the same time, since when one is bad, it puts a heavy load on the other, causing it to burn out as well.
Do I have to remove the seat to check further?
That is the best way to do so, yes, but you can try to get at the connectors for the elements with the seat still in the car. It is a little tight, but you can access them. What you want to check for is an ‘open’ in the element itself by checking for continuity between both terminals at each connector. I believe the specification is 1.5 – 5.5 ohms resistance.
Ok thanks I’ll check Thanks. Should the on/off switch show as being energized even throgh the seat does not work? Final question?
usually the switch will still light up when the element is bad or another problem exists.
Thanks. It’s back to the seat wiring. Thanks very much.
