hi im new here and i just came from another forum and i have a question about the heat in my work truck its a 87 flatbed with the 6.9 and c6 and also a wireing nightmare idk what the previous owner did but all the wires are everywhere
when we got the truck about a year ago and none of the heat controls on the dash worked and i needed it to plow and we couldnt figure out why it didnt work so we rigged the heat into an on off switch just to get through the winter and it doesnt always work good but i havent touched it since and its comming to that time of year again...also when i glow plug the truck the heats on but when i start it the heat shuts off and it wont turn back on untill i put the truck in gear
what would cause all this
thanks in advance - tj
