Clogged heater core? Pull both heater hoses and put a garden hose on one side. If it doesn't flow out the other side, replace the heater core. That should be simple, it comes out from the inside under a cover, easily.
 
Be careful, a garden hose has 30pounds pressure or more, the truck system is set to 15 max then it comes out past the cap. Don't blow up a heater core with too much pressure.
 
Does the truck have a cut-off valve on one of the heater hoses? Is this working?

i don't have a heater control valve, my heater core hoses run from the water pump to the heater core, and from the thermostat housing to the heater core nothing in between.

A/C Runs Constantly by drosnick

The A/C on my 2005 4 cyl., auto, Ranger runs when the selector knob is in the dash vent/ underdash position and also when in the windshield/down position. What's wrong here?

I may have the answer, or may not because I'm not sure I understand your question.
 
Ranger AC switches are strange, it that they are a 'push in' to turn on, and 'push in again' to turn off. It doen't indicate this much at all on the controls. The switch twists to control the air output - max, dash, vent, defrost, etc, but you have to push this switch to turn it on or off.
 
Don't feel bad, the first Ranger I test drove I returned and told the deal the AC didn't work. The salesman leaned in, pushed the knob, and said 'Yes it does'.

Just quit. Checked and found that when turned on clutch on compressor engages and turns 2-3 times, then releases. After a few seconds cycle repeats. Is there some over/under pressure switch that causes the clutch to release? Any ideas about problem appreciated. Really don't need to go to a repair shop and have parts replaced until they get lucky. It's to close to Christmas.

Norm

Low on freon charge acts like this. And, yes, a high-pressure switch turns it off.
  
Find the leak and recharge. Or, just throw a can into it and see if this fixes it.
