Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
There has been a service bulletin for that type of concern. It involves a reprogramming of the driver seat module. The dealership (stealership) would have to do that, I hate to say.
Here is what it states.
Bulletin No.: 05-08-50-008
Date: August 19, 2005
All with Seat FRT, Individual (Non BKT) (RPO AN3)
2003-2005 HUMMER H2 with Seat, Front Bucket Deluxe (RPO AR9)
Some customers may comment that occasionally the seat heater will not operate when activated. If the ignition key is cycled OFF and back ON again, the heated seat will operate correctly. Also, on some LB7 diesel engine vehicles, the seat heater may turn itself off during the first 10 minutes of operation. This occurs only with the first activation for the day and works correctly with subsequent activations immediately after the event. These conditions are intermiffent and DTC B3941 may be set.
Technicians are to reprogram the driver seat module with an updated software calibration. This new service calibration was released with TIS satellite data update version 6.5 available June 13, 2005. As always, make sure your Tech 2(R) is updated with the latest software version.
That would be the first thing that I would do, (reprogram) and it normally pays about .7 hrs. (seven tenths) and they will get an average of $75 an hour.
There is a chance that the element is bad, but the programming is what the manufacturer has determined to be the fix
That's fine. You can log back in on this post at any time. You just may get a reminder after a couple of days. Just want to make sure that it gets fixed. Also, the way to diagnos it would be with the Tech2 scan tool anyway. Since the seat back and the cusion heater are seperate, and there are problems with both, I would think that the programing it would do the trick. If not, the heater elements and labor are more expensive.
Ok, thanks, XXXXX XXXXX log back in soon!
I have an appointment for my truck on Monday Oct. 26, 2009 for the reprogramming. If it works, I will accept your answer! Thanks again!
No this is not related to the heated seats. I read all the responses and you have an element out. I would be VERY surprised if it is not.
As for your assurance that you will come back, it has been my experience that 90% of the customers that say that, don't come back. You can reply and I WILL answer you after you accept.
Well I'm surprised because I already paid into this website, what good would it do me to not accept. I will try to test the circuits you told me. When I get the readings, if they are not in the parameters, then you are right and I will accept. If they are within the parameters I will let you know as well, so I can try whatevers next.
I sent this question in a few weeks ago and already brought it to a dealership and had them reprogram the seat module per the last mechanics instructions, that cost me $75. I told the mechanic that, and he did not have any further help for me. I definately will pay when I get help with a correct diagnosis. If you were me, Im sure you would do the same. Think about it. I could get any answer from someone on this website, which is new to me. Once I accept and the problem still exist, where does that get me. So please be assured that I will accept your answer if you help me find the problem!!!
Ok, there are 6 terminals in that connector. Test the end ones.
Also 3.9 is good, but that is only the seat base, what about the back?
No, truck off. Have you traced the wires to make sure you are on the correct connector? Are you testing the correct side of the connector? The side with the female connectors?
Great minds think alike!
All you need to do is in the first line of your Question state"For BlueGorilla only". If you use the link to do this below, it will also send me a message stating that you have asked for me.
