Problem: 2013 Smart Fortwo 451 Pure experiences intermittent heating and cooling issues: heat switches to cold air in winter, and AC switches to hot air in summer.

Solution: unresolved

Key facts: - Vehicle has 62K miles - Heat does not blow strongly and switches to cold air - AC does not get very cold and switches to hot air - Suggested diagnostics: cycling the temperature switch multiple times, checking cabin air filter, measuring vent air temperature with AC thermometer (should be 35-40°F at 70°F ambient), verifying coolant level, checking refrigerant charge at AC shop - Similar issue reported by another user 7 years prior that stumped dealership technicians multiple times
