Hey guys, does anyone know what heater motor I could use to replace the factory to move more air? I was thinking of using something like I got in my 95 ..?

The heater on high is more then enough. Just put a toggle switch on it.

check your rad to be full and the air tubes behind the dash if the heat isn't there.

I can cook eggs on my floor when it is on.

I'm getting lots of heat it just not blowing enough air to keep the windows clear

If it is the def on the windows your vent tubes behind the dash are probably dryed out and toast, leaking air.

OR

The resistor switch is probably toast. Do you get low to high?
You can bypass the switch...run a wire to the fan from the fuse box and put a toggle switch someplace. For more current run it from the battery with a fuse at each end and a toggle switch in the cab.

I'm going to pull the vent tubes off and check them out.
I like the idea of the toggle switch I'm going to try that
