WEITARI A/C Refrigerant Pressure Transducer Switch for Ram/Wrangler — Direct-Fit 68083824AA Replacement, 12-Month Warranty

WEITARI 68308727AA / 68141376AA is a direct-fit A/C refrigerant pressure transducer switch designed to replace OEM part 68083824AA on select Chrysler, Dodge, Jeep and Ram models.

This compact pressure switch monitors refrigerant system pressure and communicates that data to the vehicle’s HVAC control circuit, helping the system engage or protect the compressor. The WEITARI unit is sold as a single replacement part and comes with a 12-month warranty. It fits a wide range of model years across Ram, Wrangler, ProMaster, Journey and other Chrysler-family vehicles — making it a practical spare for repairs or maintenance.

How do I know this switch fits my vehicle?

Confirm fitment by matching your vehicle’s year, make and model against the listed compatibility and by verifying the OEM reference number 68083824AA. The switch is a direct replacement for the listed models and model years; electrical connector and mounting match the original equipment specification for those vehicles.

• Check your current part number against 68083824AA.
• Compare connector shape and pin count to your old sensor.
• Review the compatibility list for specific years and models (Ram, Wrangler, ProMaster, Journey, etc.).

What exactly does the pressure transducer do and why replace it?

The pressure transducer detects refrigerant pressure and sends a voltage signal to the HVAC control module so the system can cycle the compressor and maintain proper operation. Over time, sensors can fail from vibration, heat, or contamination, causing intermittent A/C engagement or system lockout. Replacing a faulty switch restores reliable pressure feedback to the vehicle’s control system.

• Restores accurate pressure reporting to the HVAC module.
• Prevents compressor over- or under-pressure conditions handled by control logic.
• Eliminates intermittent A/C operation caused by faulty sensor signals.

How difficult is installation and what should I prepare?

Installation is straightforward for a competent DIYer with basic automotive tools; it typically involves locating the switch on the high- or low-pressure port, disconnecting the electrical connector, and unthreading the old sensor from its port. Always relieve system pressure through qualified service before removing refrigerant-side components, and confirm electrical connector fit before final assembly.

• Tools: wrench set, safety glasses, appropriate connector tool if required.
• Precaution: service refrigerant only in accordance with local regulations; use a certified recovery system.
• Test: verify A/C cycling and system pressure readings after installation.
