How difficult it is to change the bottom and back heating elements on 09 tahoe ltz? I have part numbers of 20792748 and 20792749. Is there any videos on this?

So the dealer said i had heating elements but i did some research and found out since I also have cooled seats i have teds. How can i tell if they are bad ? Had the dealer check it out but they obviously don't know anything.

Phwtt! Big help the dealer was. If you have TEDs (thermal electric devices) I'm sure the parts guy doesn't care about you because it's over his pay grade to help you.

Aftermarket cooled seats are set up to run the TED in both directions to heat and cool. I can't get a definitive answer on how GM seats are heated when they have the cooled seat option. The C7 Vette uses a standard heated element with cut outs for the cooled TED air.

It took a little digging. The Escalade uses the TED for cooling only.

The NNBS (07-14) uses conventional heated seat mats NOT the TED.


The
Escalade would have seat heating elements similar to the one above for the C7. Check out the thread below on diagnosing an 09 Escalade heated / cooled seat.

Correction… 07-10 uses TED for cooling and heating. In 2011 vented seats were the only option with resistance mat heaters. 2011 also saw the airbags integrated into the seats.

The NNBS (07-14) uses conventional heated seat mats NOT the TED after 2011.
