DESCRIPTION Hill Start Assist Switch

BRAND Mack
PART NUMBER 23229514

Function of this part

Electrical and electronic components distribute power, control circuits, and communicate over the truck data network. Modules, harnesses, sensors, and switches all work together to support engine, chassis, and cab functions.

Why this part matters

Modern trucks depend heavily on electronics. A faulty module or harness can cause intermittent issues, fault codes, or no-start conditions, so good OEM electrical parts are valuable for diagnostics and repair.

About the brand

Mack is known for building tough trucks and components for construction, vocational, and highway fleets that need reliable performance day after day.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Soft, Cool, and Comfortable for Everyday Sleep
Color: White, Size: Queen Size Set of 2
These pillows feel soft and comfortable without being too firm. I like that they stay cool during the night, and the cotton fabric gives them a nice hotel-style feel. So far, they’ve kept their shape well and feel great for everyday use.”

Best Pillow Ever! Highly recommend!
Color: White, Size: Queen Size Set of 2
These are the best pillows I’ve ever had! I have slept better than I’ve slept in years! I sleep longer and more sound. They are the perfect size and fluffiness but allow for easy movement. Absolutely highly recommend!

Soft and Restful Sleep
Color: White, Size: Queen Size Set of 2
I’ve been using this set of pillows and I really like the comfort they provide. They are soft to the touch but still offer the right support for my neck and head, helping me sleep more relaxed and wake up without tension. They also feel cool throughout the night, making my rest more comfortable and uninterrupted. I love this pillows!
