I recently replaced the thermostat in my 1998 Ford Ranger 4 Cyl. 126,000 Miles. The engine was running cold and now it runs just right. But the heater will not work. I had the control valve replaced a few months ago and I think the guy may have messed it up. Where is the heater control valve on this thing? Do you think that's the problem?
