BUICK

Clifford Auto Parts supplies programmed Buick engine computers — PCM, ECM, and ECU modules — for the LeSabre, Century, Regal, Riviera, Park Avenue, Enclave, LaCrosse, and more. Every unit is matched to your vehicle and flashed to your VIN before it ships, so it installs plug and play with no dealer visit and no extra programming.
Each Buick module is a genuine OEM part, refurbished and bench-tested in-house by ASE-certified technicians, updated with the latest software, and backed by our lifetime warranty and free domestic shipping. Whether your Buick has a check engine light that won’t clear, a no-start, rough idle, or shifting trouble, a correctly programmed replacement computer gets it running right again.
