Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The problem you are describing can be caused by any of the following,
Climate Control Seat Module (CCSM)
Climate Control Seat Module (CCSM) Wiring
Connector C305
Drivers Seat Back Heater
Drivers Seat Cushion Heater
Passenger Seat Back Heater
Passenger Seat Cushion Heater
In order to determine which is failing you are going to need to do some testing, I have enclosed the test steps in the link below, copy and paste the link to your browser to open and view them. The CCSM controls both front seats, and is located under the front passenger seat. It has three Black connectors.

Is there a fuse to look at first?
Expert:  Ron replied 2 years ago.
The only fuse that sends power to the Seat module is the 10 amp fuse in the under dash fuse panel (#25).
Customer: replied 2 years ago.
I won't be where the truck is for three hours. I'll do the check you suggested and message you back.
