Heated Seats

[beastie]

Bought my H2 a couple of weeks ago, it was 90 degrees out at the time so I didn't check the heated seats......

At the dealer they said that the seats had been re-upholstered and the heat seat components had been stripped. They can fix but it will cost $2500.

Question: Can I swap in Escalade, Tahoe, Yukon, Silverado, Avalanche, etc. seats they all look similar except for the cover "design".

-or-

Can I add the "tahoe heat pads" (saw that mentioned) and is it plug and play? Is it true that the hummer seat heaters are integrated into the cover? I do have the service manual so I can trace and splice wiring.

Thanks in advance for the help
