No heat

Ok, so I bought my rig with no heat. The fan blows still, there is just no warm air coming in. What could it be?

Are the hoses hooked up?
When the heater core goes some people by-pass it.
You can read about Heater Core replacement on my site in the Tech Tips area.
Don't let it scare you. It's easier than it looked.

Edit:
Make sure the cables are actually moving the baffles. If a cable broke it might be easy to fix.

Hi, just saw your tech article. Thanx, but there is NO WAY I am attempting that. Looks like way too much work. This doesn'thave to be my DD in the winter, so I am not going to bother with it. I'll install a couple of supplementary heaters for the odd time I drive it, and call it a day.

I am contemplating changing the T-stat. As with some other vehicles, does it have to be OEM, or can it be aftermarket? What's the best/cheapest place to order it? Can I just get it from a local parts shop?

If you get an aftermarket one make sure it has a little hole in it, if not just drill one and make sure it's installed facing up.

How's the temp gauge? Is it below normal (mid section)?

Hmmmm, than I would bet it's the thermostat.

Remove the thermostat when the engine is cold and if it's in the open position then that's your problem.

OK, it turns out I have heat.
Here is the weird part.

I can only get the heat to come out of the upper vents on the top of the dash. The main vents facing the cabin only have cool air coming out. I can get them to blow but thats it.
ALSO, my upper vents blow only whern moving. Seems like the blower fan is not working in any speed when trying to get hear or outside air.
BUTm, if I put it on A/C, I can get it to blow really hard on the fastest speed.

What could all that be?
Some sort of a resistor?

The heat and AC are separate.
The AC blows from the dash vents.
The heat blows to the wind screen and feet.
If you only have one speed on the fans it's the resistor and is a common failure.
My Rangie has the same problem.

resistor change

I also have that one speed fan problem. I bought the resistor pack but a little hesitant about taking the decker off. Has anyone done this swap ? Do you have to remove the hood also ? I remember a guy who had done it through the outside vent, but getting those rusty leads off looks difficult.

I replaced it on mine. I just went through the vents on the front. I suggest doing it if you have nimble fingers. but all in all it wasn't that bad. I put in a proline reostat from rovers north. It works like a champion now.

The weird thing is, it won;t blow through the vents on top of the dash. It's like the blower is dead, but it works through the main vents.
Could that still be the resistor pack?

There is a fan in the heater box. AND a fan in the AC housing.
So you have two fans one for heat and one for AC.

Ok, so how difficult is it to swap the heater blower. Do i have to rip the dash off, or is it simpler than that?
Where can I get a blower?
