Question about Ford PUMA
No heat or low heat in a water cooled engine is worthy of an immediate check as major damage to engine could be the result of continuing to drive it. Things to check:
These two things may cause no heat and possible not ever show as a problem on the temp gauge or temp warning light until far to late:
Low coolant/antifreeze level
Other possibilities that may/may not show other signs of trouble as well:
Failing water pump (this would also explain some noise, typically like a grinding, scraping or bad bearing noise)
Slipping belt (Typically associated with the famous belt squealing or chirping noise)
Clogged radiator and/or heater core
Non-operating temperature control valve
Hope this helps!

How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

SOURCE: Heat not working
If jeep is a limited model it has automatic temp control for the heater blend door, it is controled by a electric motor, and can be problematic with age,sometimes it makes a clicking noise when the blend door is stiff ,which then it must be lubed and freed up

Since warm air eventually comes out when the vehicle is in motion, you may have an air mix door that is stuck in fresh or is somehow blocking warm air from the heater core.
To see if the air mix control motor is bad, you need to retrieve your Diagnostic trouble codes (DTC's) from the heater control panel. To run the diagnostic function, do the following:
1. Turn the ignition switch ON (II).
2. Turn the fan switch OFF.
3. Press the recirc control button to select Recirc (recirc light on.)
4. Press and hold the recirc button to select Fresh (recirc light off) and continue to hold the button down until the recirc light comes on for two seconds and then goes off.
5. If the system is okay, the recirc light stays off.
6. If there is a problem, the recirc light blinks the DTC to indicate the trouble. One blink=a problem in the air mix control motor circuit. Two blinks=problem in the mode control motor circuit
Three blinks=problem in evaporator temp sensor circuit.
7. Turn the ignition switch off to cancel the self diagnosis function. Run the diagnostic again after repairs are complete.
Note: the air mix control motor has a rod which connects to a plastic link. The link controls the mix doors and also connects to the heater control water valve via a cable. The air mix motor may check okay, but if the link is broken then you will still have problems. the motor is on the bottom of the heater unit in the front passenger's foot well.

Sounds like a thermostat problem to start with. Follow the top rad. hose to the engine. You will have to bleed the system of air after.
