HEATER WON'T GET HOT

1999 Mercury Sable

Heater problem
1999 Mercury Sable 6 cyl Four Wheel Drive Automatic 100000 miles

My Heater blows cold air, won't get hot. Heard
a popping sound while I was driving, like a backfire.
heater won't work since then, but air works fine.

Try replacing the thermostat and if it has heater control valve check that too.
