Detailed Description

Cardone 40-438 is a remanufactured windshield wiper motor engineered for Jeep applications that need OE-style operation and fitment. It is built to match original equipment performance, making it a direct replacement choice for front wiper service on the 1991-1999 Jeep Cherokee and 1991-1992 Jeep Comanche. If you are searching for a Jeep Cherokee wiper motor or a Jeep Comanche front wiper motor, this unit is built around the original design requirements.

The remanufacturing process focuses on the parts that affect motor output and durability. Bearings are serviced or replaced, magnets are recharged, solder joints are reflowed, and the output gear receives lubrication to support long-term operation. Cardone also tests the major internal components against OE standards before final vehicle-level function testing.

This part cross-references Jeep OE numbers 4723460 and 4856478 for the same application.

Common Problems This Part Can Address

• Wipers that stop mid-sweep or park incorrectly
• Slow, weak, or inconsistent wiper movement
• No wiper motor operation during rain or snow
• Intermittent front windshield wiping on Jeep Cherokee or Jeep Comanche
• Noise or binding from a worn motor assembly

Installation Notes and Tips

Confirm the vehicle uses the correct front wiper motor application before installation. This unit does not include a washer pump, and Cardone notes that some systems will not operate properly if the washer pump is defective. If the motor does not have hidden wiper blades, parking misalignment is often related to crank arm position; adjust the crank arm angle on the motor shaft and follow a vehicle-specific service manual for the hidden-park reset procedure.

For moisture-sensitive systems, verify whether the vehicle uses a rain sensor mounted inside the windshield near the rearview mirror. If the original concern involved a nonworking motor after washer pump replacement, bench test both components before replacing either one.

Quality Assurance

Each Cardone remanufactured wiper motor is re-engineered, tested, and built to meet OE performance expectations. The process includes component-level inspection, final function testing, and remanufacturing practices that reduce material and energy use compared with producing a new part.
