Most heating and air conditioning problems announce themselves well before they strand anybody. On a 2013-2019 XTS, these are the ones worth acting on.
1. Air that is cold at highway speed and warm at a stoplight
By the time this is obvious you are generally replacing more than one part. Start by looking at blower motors.
2. A musty smell for the first thirty seconds after startup
This is the symptom people put off longest and regret most. Start by looking at cabin air filters.
3. Air that only blows on the highest fan setting
By the time this is obvious you are generally replacing more than one part. Start by looking at blower motors.
4. Vents that will not switch from defrost to floor
This is the symptom people put off longest and regret most. Start by looking at A/C compressors.
5. A clicking or ticking behind the dash when you change temperature
It rarely gets better on its own, and it usually gets louder before it gets expensive. Start by looking at blower motor resistors.
What to Do Next
Cabin air filter every 12,000 to 15,000 miles, or annually. In North Texas with construction dust and cedar season, annually is the honest number.
Rear climate content, heated and cooled seats, and tri-zone systems all change the parts list.
