03 Durango engine not cooling & blowing cold air w/ heater on
I have been having a strange issue with my durango for the past couple of weeks. It started off with a rattling noise coming from the engine compartment but now has gotten to another level. The truck is now over heating and the heater is now blowing cold air. Now today I changed the termostat and radiator cap (just for good measures) but its still over heating. I checked the water pump but thats working and not leaking. I was thinking the fan clutch could be the issue but I'm not sure.
Any help would be greatly appriciated.

the fan clutch is an easy check , open the hood and try to spin the fan, if it spins more than 1/2 a turn (after you stop pushing it)the clutch is bad (for reference mine stops turning pretty much as soon as you stop pushing it),
have you tried flushing the heater core? it could be clogged causing the low heat, and if the hoses are clogged at the right place this could also be causing the overheating if the radiator is clogged, so flush the cooling system and replace with a 50/50 mix of anti-freeze and distilled water

Well I added some fluid to the vehicle and still having the same issues. Going to take it to the shop and get it checked out and possibly a flush and fill. When the air is on heat in the car there is a funny smell like something burnt coming from the vents. Any help would be greatly appriciated.

Well you let the reservoir go dry so it has air in the system. You need to keep the reservoir full and get some antifreeze in the system possiblly burping the system if it is a 4.7L. Speaking of which, what motor and year do you have?
One thing you can do is open the radiator cap and fill the system.
BTW<----- You should listen to your dad.
