The heater does not blow hot air when I let my Toyota Tacoma 2007 idle in morning for 15 minutes. The outside air temperature is about 24 degrees, the heater blows air that is light warm. Is this normal. I have already replaced the thermostat and water pump, but same problem persists?
Heater does not blow hot air after idling for 15 minutes on cold mornings. Heater blows
hot air when driving, but the air cools down to warm when I stop at a signal light. I have
already replaced thermostat and water pump. Is this normal for Tacoma? Should the
truck blow hot air after idling for 15 minutes on cold mornings, 24 degrees?
