Front Heated Seats Not Working Consistently

[CslRkH2]

"Could it be the lights?" Not yet, I haven't connected them to any power or grounding source yet. There just installed on the rack and wired to a quick disconnect at the rack. Haven't gone into the engine or cab yet.

To be honest I don't know when the last time they work "consistently" was. Its been way too warm here to need them until the past couple weeks. What is strange is that in the past couple days sometimes they work and sometimes they don't.
