    My 2003 Buick Lesabre heated seat quit working. Then the passenger heated seat quit working. Now the fan is only blowing cold air. I replaced the fuses. How can I check a relay?

SOURCE: 2003 buick lesabre heated seats wont work

I had this problem, but only on the driver's side (with leather seats). Sometimes the switch would come on, but I could not get it to go back off (and the seat would not heat).

I ended up removing the drivers front seat cover (only the bottom part), folding it back from the driver's door to the middle of the car. You also have to unplug the wiring harness underneath the seat. I found a black spot burned in the foam. This is where a wire had broken. I carefully pulled the wire together, then soldered it. I put everything back together, and it has been working ever since (about 6 months - and getting lots of use in the middle of the winter).

I think the only way to replace the heated seat wires is to replace the whole seat cover. I was glad I could fix mine by soldering it.

Heated Seats


I had the same problem on my 04 LeSabre. To check to see whether it was the element or the switch, I unplugged both seats and ran jumper wires to make left switch control the right element. The switch and element worked properly. Then I ran jumper wires to make right switch control the left element. The problem was the same, so it was the element was bad.

I had my element replaced at the dealership, since I didn't want to wreck my leather seats. It cost over $400 (about $150 for the element). I guess it just tucks next to the old element - the old element stays in place.

Buick Lesabre Heated Seats not working


The problem is most likely caused by shorted heating grids in the seat cushion itself, kind of like the heating element in an electric blanket, very expensive to replace.

How to repalce the battery


This is simple to do once you find the battery. Remove the rear seat (pull up on the front of it to release) to expose the battery. Then remove the Negative terminal followed by the Positive terminal. Finally remove battery hold down bolt to free the battery. ALWAYS wears eye protection when working on/near/with the battery.

Note- The seat belt configuration in the seat before removing... don't forget the seat belts when installing.

Use battery terminal protector on the terminals. Thoroughly inspect the terminals for signs of corrosion. Replace as necessary.
