This can result from heater core blockage. If it is partialy blocked, you may notice a little heat with the fan on low, but it goes cool when the fan speed is increased. Other signs of blockage may include engine temperature fluctuation, and/or excessive pinging (pre-ignition). This can also be caused by the engine thermostat being stuck in the open position.

On my 1994 Ranger, the heater core is directly underneath the glove box. All you do is crawl underneath the glove box, losen 4 screws in plastic housing, and pull the housing off. Make sure to losen to hoses underneath the hood located on the firewall to drain the antifreeze. Once this is done pull out the heater core. Mine was fairly easy and took under an hour. I hope this helps somebody. 1993 and 1994 Ford Rangers have the easy out Heater core anything after you have to take the entire console out with the dash.
