Heated seat issue

[Nick05LT]

I have an 05 LT w/leather heated seats. Both seat backs work on all 3 settings. But when I try to use both bottom and back warmer they turn off after 1 minute unless they are on low. Any suggestions on what this can.

I had the same thing on my 03 sierra and yukon on the driver seat bottom. I had to replace the heating element that attaches under the leather cover.
