Not blowing heat.

My 2004 6.0 was blowing hot air out the heater before I did my egr delete oil cooler and studs and now after its not blowing. I can feel hot air coming out the bottom by my glove box but it won't blow out the vents. Any idea what could cause this? Cold air blows but no hot.

So you can get air to blow out the vents, just not hot air? If so it sounds like an air pocket when refilling coolant. The best thing to use is a coolant lift. It pulls the system into a vacuum and then refills, ensuring all of the air is out.
