Heated seats inoperable

[Hacim007]

TSB #050850008 was a service bulletin put out in late 2004.

I'm having problem with the heated seats. They used to work fine now they shut off after a few seconds on either side. I can't find out the full details of the bulletin because I'm guessing u have to be a dealer or have access to view the full description. Anyone else had this problem and solved it or figured out what the problem was?

Anyone?

I am having an intermittent issue where my drivers side heated seat comes on by its self. Shut it off, and then couple of minutes later it comes on again by itself. It does not happen all the time, or every day. Any help would be great!

... and on my driver side, the lights act normal, but the bottom will barely even get warm and the back doesn't come on at all. My list is getting pretty long its almost dealer time.

Condition
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 intermittent and DTC B3941 may be set.

Correction
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® is updated with the latest software version.
