2007 Silverado 1500 No Heat

Hexa Fox · November 26, 2014

Hey guys I am sure this has been asked here before but was wondering if I can get some things to check now. It is starting to get cold again here in West Virginia and this year I am offering snow removal to clients. We are getting close to that time where I am carry out this service.

Anyway I have been having trouble with the heat in my 2007 1500 4.8 V8 1500 Silverado, and by the way it is the new body style now the classic. Okay well what happens is I can not get my truck to blow hot air. I have already seen it mentioned a few times it will actually blow cold air, not neutral air, COLD air. As you may have imagined this is extremely frustrating and this year it will be much worse as I have to leave my truck to use a snow blower and shovel and would like to be able to return to a warm vehicle, not one that is colder than outside.

Anyway I am just starting to use the heat in it now. Sometimes it works fine and other times I can not get it to blow heat at all. However when it does blow heat it is like you would normally expect. It is not any colder or anything. It seems like it is more likely to let me down on especially cold days. Are there things that I can start looking into to actually see if they are the cause? I am trying to get ahead of it now so if I start experiencing it I can start troubleshooting with help off here and hopefully get it fixed.

If I can start visually inspecting things like clogged hoses, thermostat, fuses, and the like I will and if I see anything that could cause the problem I will replace and see if it works. I would not mind cheap easy fixes right now before I even start troubleshooting either. For example if I know there is even a small chance that something as easy as a fuse is causing this issue I will go ahead and replace that sort of stuff before I even let this problem happen to me again. Any help would be greatly appreciated!

It might be an air bubble or you might need to flush the heater core both ways but if you have not done this before you should really seek professional help or it could be something a little more complicated

Okay cool deal, I have a few local mechanics I trust. Because if the snow removal business works out I may mount a plow to it. Right now I am going to be leaving the truck and I would obviously be nice to return to a warm truck and not a cold one.
