Common Causes Of Rear Ac Not Blowing In 2018 Dodge Grand Caravan
The 2018 dodge grand caravan is a versatile and reliable vehicle, but like all machines, it’s not perfect. One of the most common issues that drivers encounter is the rear ac not blowing. This can be inconvenient and uncomfortable, especially during hot summer months.
In this article, we will explore some of the most common causes of rear ac malfunction in the 2018 dodge grand caravan.
Inadequate Refrigerant Levels Due To Leakage
One of the primary reasons for rear ac not blowing in the 2018 dodge grand caravan is that there may be inadequate levels of refrigerant due to leakage. This can happen over time, but it can also be caused by a faulty seal or component in the ac system.
Signs of this issue include warm air blowing from the rear vents, unusual noises, and a decrease in ac performance.
To fix this issue, a professional mechanic should inspect the system, check for leaks, and recharge the refrigerant if necessary. Replacement of faulty components may also be necessary.
Malfunctioning Ac Compressor Clutch
Another possible reason for rear ac not blowing in the 2018 dodge grand caravan is a malfunctioning ac compressor clutch. This component is responsible for engaging the ac compressor to cool the air. Signs of a faulty clutch include a decrease in overall ac performance, unusual noises, and a burning smell.
To remedy this issue, a professional mechanic should inspect the system and replace the clutch if necessary.
Clogged Or Dirty Ac Air Filter
A clogged or dirty ac air filter can also cause the rear ac not to blow in your 2018 Dodge Grand Caravan. The air filter’s job is to remove contaminants and impurities from the air before it enters the cabin.
If it becomes clogged or dirty, it obstructs the airflow, reducing the effectiveness of the ac system.
To fix this issue, the air filter should be inspected and replaced if necessary. It’s recommended to check the filter regularly and replace it every 15,000-30,000 miles.
Broken Blower Motor Resistor
Finally, a broken blower motor resistor can also be a cause of rear ac malfunction in the 2018 dodge grand caravan. The resistor controls the speed of the blower motor, which is responsible for delivering cool air into the cabin.
Signs of a broken resistor include the ac fan only working on high speed, or not working at all.
To fix this issue, a mechanic should inspect the system and replace the resistor if necessary.
The rear ac not blowing in the 2018 dodge grand caravan can have several causes, but these are some of the most common. If you encounter any of these issues, it’s important to get them fixed promptly to restore the comfort and functionality of your vehicle’s ac system.
