Hey guys, my name is Carlos and this is my first time posting on lincolnvscadillac. I've been having a problem with my ls for the last couple of weeks. Whenever I turn on the heat, cold air comes out of the vents. I searched on the web, this site primarily and concluded that it might be a bad dccv. What I did today was disconnect the dccv and still had no heat. After that I took it out and remove everything inside the dccv in an attempt to bypass it and not have to buy a new one. I put the gutted dccv back in, and the hoses that go to the heater core were warm, but I still had no heat!!! I then did the self diagnostics test on the datc and got codes 5041 and 1263. I assume that the problem now lies on the climate control module, because even with the gutted dccv I had no heat. I believe that code 1263 has to do with the cold air door, but I don't see how that would affect the heater, and then code 5041 has to do with the speed input. Before proceeding to buy a new one, I wanted to see what you guys had to say. Thanks in advance.
