- 2001 ford explorer sport
2001 ford explorer sport 4.0 Litre s.o.h.c. Had same problem last month. Noticed the temp. gauge wasn't hot enough I replaced the thermostat. Now temp. is O.K. But the heater works most of time, then sometimes it doesn't work at all. Very Cold. No response from heater temp control blend controls. temp control doesn't respond at all. Radiator is full ,and heater hoses are warm. When it work's fine, it get's Plenty of heat .When no heat, it's really cold air from vents. noticed the A/C clutch is cycling when the heat is on??? Thought the A/C should run when A/C is selected, or when Defrost is selected.?? Not when the heat is selected??? Need some Help. Also should there be vacuum going to the heater hose control valve when heat is selected.???
