Causes of heater problems not being able to heat car

Hi this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team! Uh oh, that's no fun during the cold months. There are a few suspects depending on your specific A/C system, with a manual system the most likely suspect is the heater core itself. I did some research on your vehicle and found that coolant is directed through the heater core at all times, so that would mean there's likely to be a clog somewhere. If your vehicle is equipped with Auto A/C then there's possibly an issue with the blend doors, but the heater core remains a possibility. A thorough diagnosis by a competent professional is always recommended to confirm the source of the issue, before any repairs are attempted.
