How to Troubleshoot a Dodge Grand Caravan Rear AC Not Blowing

To fix the problem with the Dodge Grand Caravan’s rear AC not blowing, check and clean the air vents or have a mechanic inspect the air conditioning system.

Dodge Grand Caravan Rear Ac Not Blowing

The Dodge Grand Caravan rear air conditioner not blowing is a common issue and can be easily fixed by following the right steps. To address this issue, you need to first turn off the air conditioner and inspect the condenser and evaporator core fins to make sure they are clean, and there is no debris or obstruction blocking airflow. Secondly, check the refrigerant level to ensure it is within acceptable levels. Next, you must inspect the blower motor relay and fan motor for any signs of damage or worn out parts. Finally, if these checks show no issues with any of the components, you may need to replace either components that have worn out. Following these steps should help restore your rear AC units functionality.

Diagnosing the Problem

When your Dodge Grand Caravan’s rear air conditioning isn’t blowing, it can be frustrating. Fortunately, diagnosing the problem is the first step in getting your AC back to normal. The most common cause of an air conditioner not blowing is a malfunctioning blower motor. To determine if this is the case, you’ll need to check the blower motor and inspect any related fuses.

Testing the Wiring Connections

Once you’ve confirmed that the blower motor is working correctly, you’ll need to test the wiring connections. This includes examining the power supply and investigating ground connectivity to make sure all wires are properly connected. If there are any shorts in the wiring, they will need to be resolved before continuing on with other repairs.

Fixing Shorted Connections

When dealing with shorted connections, it’s important to trace and replace any damaged wire harnesses as well as secure any pin connectors and ports that may have been affected. This will ensure that all wiring connections are up to code and safe from further damage or disruption.

Examining the Resistor Module

The resistor module is an integral part of your air conditioner system and should be inspected for signs of wear or failure. If a resistor block has failed or become worn out, it should be replaced with a new one as soon as possible. Additionally, all ports and contacts should be securely reseated in order to prevent further issues from occurring down the line.

Replacing a Malfunctioning Blower Motor

If all else fails, you may need to replace your blower motor unit altogether. To do this, you’ll first need to locate the blower motor assembly within your car’s compartment before removing any fasteners for accessibility purposes. After changing out the unit itself, you’ll then want to secure any new fasteners and gaskets before finishing up reassembly altogether.

Ensuring Ventilation Flow Is Unrestricted

If you have a Dodge Grand Caravan and the rear AC is not blowing, one of the first things you should do is check the ventilation flow. This may require cleaning out clogged vents and HVAC modules with a vacuum cleaner. It is also important to make sure there are no obstructions in the vacuum blockage areas.

Examining AC Condensers for Blockages or Corrosion Problems

Another step to take when troubleshooting why your Dodge Grand Caravan rear AC is not blowing is to examine the AC condenser for any blockages or corrosion problems. This can be done by removing the outer cover and checking for debris, corrosion, or deteriorated internal parts. If any of these are found, they should be addressed before proceeding with further troubleshooting.

Refilling System with Refrigerant

In some cases, it may be necessary to refill the system with refrigerant in order to ensure proper air circulation in your Dodge Grand Caravan. To do this, you will need to drain old refrigerant from the system and then fill the AC compartment with fresh refrigerant. Make sure that all safety precautions are followed when handling refrigerant, as it can be dangerous if not handled properly.

Final Adjustments To Restore Air Temperature Control to Normal Levels

Once everything else has been checked and addressed, its time to make some final adjustments to restore air temperature control back to normal levels. This includes adjusting thermostat controls back to factory specs as well as testing operational temperature sensors. Once all of these steps have been taken, your Dodge Grand Caravan should once again be providing cool air from its rear AC system!
