Heated seats

[Rick Shammel]

The heated seats on my 06 Laramie act funny. When it’s colder outside the button lights will flash saying there is a fault. If it’s around 50 degrees and up I have zero issues and both passenger and drivers side work fine. They only stop working when it’s cold.

That sounds like a temp sensor issue.

Or a ground issue with connector loose. Time to get a multi-meter and start checking. Electrical will drive you nutz! Time will be needed to find the issue. Do you have wiring diagram for your truck? If you don't, might be worth it to get manuals as this will help with the tracking down of the issue. Good luck.
