Question about 2004 Buick LeSabre

Seat Heater won't work

The drivers side seat heater on my 2004 Buick LeSabre Limited won't work. The light on the heater button doesn't even come on. Is there a fuse blown somewhere that controls this and if so where is it please? If not a fuse, what might the problem be?

    Thank you for your response. If the heater grid is bad but the
    heating light does not come on, does that mean they are connected in
    serries? Will you tell me how to test the grid please?



    Thanks

    I found there is a fuse for each of the seat heaters. One for the left
    seat heater and one for the right one. The fuse for the heater
    that doesn't work is OK . I tested it with an ohm meter.



    I said something wrong in my post. The seat heater light works
    but sporadically. It always goes on to high and by fiddling with
    it, it goes to low and to off. Does this mean the switch is bad
    or the heating element is bad? Is it expensive to have my problem
    fixed and can only a dealer do it? Your suggestion please.



    Thanks

    I took it to a dealer and the seat heater and a control module were
    both out. The switch was fine. Problem fixed for $750.

    If only one seat is not working then the problem is not a fuse, u will have to test the heating grid in the seat, it may be burnt out, let me know the results of the test.

I have found that is the grid fails the light will not light, it is not just a switch, it also has a timer circuit in it, when the grid burns out it will in most cases short out, this destroys the switch module, so both will have to be replaced to correct your problem. I base this diagnosis on 30 years of new car dealer work as a technician.

    I would try the switch 1st to try and save money, but it is my understanding that a shorted seat heating element will damage the switch, I guess it is worth the risk.

SOURCE: Drivers heated seat won' work

Probably a fuse!
Under the dash on the drivers side or under the hood.
New cars have them labeled right at the fuses not in the manual!
Hope this is helpful.

Good Luck!

How do I fix the drivers side front seat heater on a 2000 Buick Lesabre LTD? It appears to be the heating unit and not the switch.


Hello: It would be best to replace it, We fixed (per GM Instructions) but they didn't stay fixed so that's why I recommend replacing it. To replace it you have to remove the outer cover on the seat cushion. Bottom.

Drivers seat heater will not switch on. New fuse installed.


the switch works the relay, the relay powers the heater, being a 12volt heating element, it's bound to have a good size wire going to it, make sure the wire feeding that relay is hot, it will be a larger inline fuse or a fusable link,it will come off a main power source,I.E. the starter or something like that, the small fuse you replaced is for the relay curcuit,good luck

The body control module in this vehicle sees a short in the seat heater system. These vehiucles are typical of the heater wiring shorting out. When you try to use the bad heater the computer shuts off all the heaters.

You will need to install a new seat heater pad.

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.

Driver side seat heaters


This is a common problem, if the lights come on the switch ( which confirms your relay is working) then it is the heater in the seat itself. Dealer only part.
Hope this helps

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.
