Why would your 2001 Gallant only blow cold air from the heater?

Your thermostat is the likely culprit here it is probably stuck closed. Have it checked out.

Leak in heater core. Replace core.

OK, did the blower motor actually just stop, or does it still blow but no heat?

if the heater does not blow out warm air change the setting.

It doesn't really blow it out it just warms the cold air.

Poor coolant circulation from a plugged up heater core. Try flushing the heater core and replacing the thermostat.

The heater does not blow air because it emits infrared rays that have heat molecules within them, thus releasing heat, not blowing it. A heater does not blow air becasue there is no moving air source within the heater. The heater emits infrered rays that cause heat to slowly flow out of the heater.

The resitors or contacts to the resistors have quit. Start at the switch, check continuity/resistance on the input and output for each speed.

Need to check the coolant level in the Radiator, it is probley low on coolant. The heater core could be 1/2 stoped up. Can switch the hoses around on the heater core and go drive it, It will flush the heater core.

Low coolant? Bad thermostat? Heater core plugged, restricted or airbound? Bad heater control? Water pump not circulating coolant?

User Avatar

1) low coolant? 2) bad thermostat? 3) system airbound? 4) heater core plugged? 5) heater control cable broken?

User Avatar

A restricted/plugged heater core can do that. Try flushing the heater core.

Possible causes are, low on coolant, thermostat stuck open, clogged heater core or vacuum scorce not getting to the heater control.
