Get the dead animals out of your heater ducts.
Is this a noise you hear all the time or just when the heat/AC is turned on? If it just happens when your heat/AC is turned on it is probably the compressor kicking in and out. On my GMC van it was very quiet, but on my Ford Ranger it is loud clunk.
No
no heat in 96 ford taraus,new thermostat,has coolant in it
The gear shift knob on a ford Ranger is pressed on tightly. A heat gun or hair dryer can be used to heat the knob to help remove it.
change the thermostat
HEATER WISE? YOUR HEATER CORE MAY BE BLOCKED

On your 1989 Ford Ranger : The vacuum modulator valve is on the passenger side of the A4LD automatic transmission ( it might be behind a heat shield )
replace the heater core if that's not it start checking fuse
Not unless your heater core leaks.
I believe it's on the passenger side of the transmission behind a heat shield
