Smile Help with my ranger!

Hi, I have a V6 4.0L and a 5-Speed Trans. The problem is when i start my car and start driving after a while smoke starts to seep out of the vents. And this is with the heat selector switch in the cold position and the blower motor off. Then if I turn the heat selector switch to hot, more smoke comes out. Then is I turn the blower on it is like somebody is taking smoke and funneling it into my car. It is not heavy smoke and it doesnt smell bad. Then for every turn of the blower motor speed the smoke amount increases. I checked around the heater core and as far as I can tell there is no liquids draining out. Also after a drive around the block with the engine at normal operating temperature the inlet hose for the heater core is all loose and is very hot. Then I go to feel the outlet hose and it is cold or slightly warmer. I noticed this problem before the smoke because I was defrosting my windows and they were fogging up and I have the heat on high and it wasnt blowing out hot air. And the engine was at normal operating temperature. Also around the inlet and outlet hoses on the firewall for the heater core there was fluid not alot but enough to stand out agianst the black dusty plastic. And if i jiggeled the hose bubbels would happen and a sound along with it. Then a tiny amount of fluid would leak out. But there is no fluid by the outlet hose.

My ideas:
-Heater core is clogged with rust from the engine(my car is 17 years old)
-Blower motor has a shorted wire and is smoking
-Bad water pump(not possible though seeing as it is mechanicaly driven off of the crankshaft)
-Leaking heater core


I think it could be a wire issue because around the time it happened i have the following electrical devices running:
-Winshield wipers(on slow speed)
-Heat on 2nd or 3rd blower motor speed setting
-Subs(which operate around 90W per channel)


Also when my car is ideling(around 500-600rpm) the radio or the headlights(whichever is on) dims on and off faintly like the alternator is bad. Is it just because my car idels so low because when i rev it the diming goes away and it is a constant light.



I know so much to read and so many problems. But to whoever can answer them THANK YOU!

All this trouble from such a little truck. It doesnt matter I love my Ranger!

for that id pick up an explorer alternator from the junkyad. they are better and bolt into the stock location. your running two subs? if so, definatley get the expo alternator, thatll help with that issue a lot

Well sad news guys. I had my car checked out by my cousin who is a mechanic and he said my heater core is leaking. So I am going to replace it. After troubleshooting everyother cause of the smoke the heater core is the last thing. And it seems the most logical. So I am going to buy a new one for about $30 dollats from LMC truck magazine and reaplce it. I will let you all know how it goes. For now I am just going to bypass the heater core and will have no heat until I replace the heater core.
