🔁 Interchange / cross-reference numbers

This is the part you really care about 👇

Your 55055482B will typically interchange with:

• 55055482A (earlier revision of same unit)

• 55037030 / 55037030A / 55037030C

• 58024B 

✔️ These are all basically the same control head with minor revisions (supplier, lettering, or internal updates)

✔️ As long as:

• Same plug configuration

• Same button layout (AC, recirc, rear defrost, etc.)

…it will work.
