I hate to even bring up the topic of grid heaters.. truck was starting hard once winter hit, and I realized (bought the truck in may) that the grid heater isn't working. I tested the fusable link from the battery to the relay, and had power, but didn't have power coming out of the relay. I replaced the relay tonight , and had the same issue, no power coming out.
Seems to me like the ecm isn't telling the relay to activate. Could this be the Intake air temp sensor? With my 'wait to start' light activating in the dash, I assumed the IAT is good
Any helps appreciated
