Default Heated seat not working

Hey guys,

Bought my 2011 Turbo4 Premium new in 9/2011 and both driver & passenger heated seats have worked fine. Until recently. The driver's side only doesn't stay on. The switch shows the heat turned on when I press it. But after 30 seconds or so, the light turns off and the seat doesn't seem to get warm. The passenger side still works fine. Any advice on how to troubleshoot?

Default Driver heated seat not working

My '11 started doing exactly this about 18 months after I got it (and right before the start of winter!).

I took it to a Saab guy and the problem was the heating element in the driver seat cushion had a broken grid. The dealer suggested he could repair it but didn't think it would work well or for long. The only option is to replace the seat heating element entirely.

From saabusaparts.com, Heating pad.(9-5 1998-2011)[12777551]. I am ordering it now and going to try to replace it myself.

Good luck!

How did he diagnose the grid? I would guess we could take a multimeter to it and check for continuity through the grid. I hate to guess.

Anyway, let us know how the install is and if it fixes the problem!

Default Seems to be a common problem

Hi guys,

We bought a 2011 turbo just a couple of weeks ago, it has 16k miles on it. Sweet car, the only problem with it is that the driver's seat heating exhibits exactly the same symptom. I'm glad I found this thread, seems to be a pretty common problem. The heater elements are cheap enough, however if 4 Saab owners replied to this thread within a day it might be a poor quality part that will break again in a short time. I decided to check if other cars built on the same platform (http://en.wikipedia.org/wiki/GM_Epsi...orm#Epsilon_II). Sure enough this tread on Buick forums confirms the same issue: http://buickforums.com/forums/showthread.php?t=23361. Of course buick owners still have their cars under warranty. I see that Buick changed part number for the heating pad for 2012 models, i wounder if they improved the part. I'm curious if anyone on this forum actually took a seat apart to replace the element, how complex this task is.

Regards,

Vlad

Just wondering if you did this yourself and how things turned out?

Vlad- good info on Buick changing the part number. If they indeed upgraded that part, I might give their new part number a try.

The Buick part (20982766) is cheap enough to try it out. Buick seats look 95% the same, i think i'll give it a shot in the next few weeks. Successful or not I will post a write up and pictures .

Default Heated seat update

Here's an update:

In my case the problem was the heater element in the seat cushion. If you wan to check yours remove the 2 torx 40 bolts that hold rear of seat tracks, slide the seat back about 1/4 of an inch and tilt it back. The connection for the bottom element is at the back of the cushion, it has 4 wires. The 2 yellow wires are for the sensor, measure the resistance between the black and the brown wire. if there's no resistance your element is bad. The seat is very heavy, cover the sill to avoid any damage. The leather cover is held by a couple of plastic ties that you have to cut and few plastic clips that are easy to remove by hand. On the inside there are plastic and metal parts that are glued to the foam cushion, remove those carefully to avoid damage to the foam. I used a Buick heater element (part number is above in this thread), which is a slightly different shape than the original. In the attached picture the original is on the left, the Buick element is on the right. Buick's part connector is different, however the wire coloring is the same, I spliced the original connector in. If you're using a Saab part for the fix I would strongly suggest to find where the original part broke and add additional padding around because there are few hard parts that contact the heater element directly. Hope this helps, this is a minor issue with an otherwise great and rare car. As a side note, the seat with all the wiring and rear video screen is far more complicated that some vintage cars I owned :-).

Nicely done! Did you pull the seat out of the car entirely?

Yes I did, the seat belt was still attached to the car though. Conceivably it could be done with the seat in the car, but you won't have much room to work.

How is the Buick heater element working out? Is it still working I was just worried the spliced wire would change the resistance and cause the part to fail.

It's working fine. Why do you think spliced wires would change the resistance? I only spliced in the original Saab plug connector, that should not have any effect on the resistance. I think the reason that the heater elements go bad in these cars is the hard parts that are in contact with elements and eventually break the grid.

My 2010 Aero is also cutting out after about 1-minute (only on drivers side). One interesting note - if I select the lowest setting (on the seat warmer) it will stay on. Do you all think this is a smiliar issue?

Does it actually heat on the lowest setting both bottom and back of the seat? If it does then it could be something else. If it's the same issue then the grid in the bottom of your seat will completely break in the near future and it won't work in any setting .

Just remembered that the Aero seats are different. I don't see how they could use the same heating element in those seats, so your problem could be something completely different if your seat looks like this: http://3.bp.blogspot.com/_J3_liDBfbv...5-Interior.jpg

Default Aero seat with adjustable leg

The part number for the seats with the leg extension is
12777552. My Saab guy ordered me the 551 which will not work at all, since the 552's main section is actually shorter and has a little tongue element/grid which goes into the leg extension.

I don't know how anyone could do it in the car, especially with all the hog rings you have to remove and reclip. There are like 20 something to get the grid out.

I pulled mine out and removed the cushion. Not too bad. I'd recommend covering the center console and inside b-pillar plastic trim with towels to keep from scratching them. Also adjust the seat to the midway point in height and length to get it out easier.

On a 4 cyl car there are no hog rings, just a couple of zip ties. Obviously the Aero cars got their seats from a better place

We repair seat heaters all the time for dealerships.

If the grid has a small burn in it, cut out the burned area, do a proper solder to make it an acceptable repair, then cover the repair with a material that is flame retardant (we use seat heater pad material, it meets those standards)

Replacing the seat heater pad entirely is definately an option, but all factory seat heaters are made with cheap wire element style pads. It's not a matter of if it will fail again, but when....
