Air intake heater relay

Can someone tell me where this is located on the truck. My truck has this code in it far as long as i have owned it. Clear it and just comes right back. Thanks in advance

The heater it is talking about is the grid heater. The solanoid's are located on the passenger battery box--lower side. The relay should be in the fuse box under the hood.
