I have a 2002 mercury sable that heater will not get hot. last year replaced a stopped up heater core and it was fine all winter. this year replaced thermastat and blend air actuator. its warm but not...
Since your blower is working and it is a heat issue,thats where we'll
start,First thing is have you checked the coolant level in the radiator when
engine is cold,make sure it is filled to top,next verify you have coolant in
reserve ,Start your van and get it up to normal operation temperature,If your
heat gauge on the dash works correctly it should be 190 degrees,Now lift the
hood and locate the two heater hoses going into the heater assembly at the fire
wall,Both hoses should be hot to hold on to,if both are hot and no heat inside
your problem will be the blend air door in heater assembly.
if neither hose
is that hot you need to replace the thermostat in the engine to get it up to 195
if one hose is hot and one is luke warm then the heater core is
blocked and to blame. hope this helps you.
