Fitment coverage includes long-tail applications such as Fits 2007-2014 Chevrolet Tahoe, N/A; Fits 2007-2014 GMC Yukon XL 1500, N/A; Fits 2014-2017 Cadillac CTS, N/A; Fits 2011-2019 Chevrolet Cruze, N/A; and Fits 2007-2013 Chevrolet Silverado 1500, N/A. It also appears in applications for the Buick Enclave, GMC Acadia, Chevrolet Impala, and Cadillac Escalade families. The 933332601 relay is a practical OE-style replacement for vehicles that use a 12V 5-pin changeover relay in body and comfort circuits.

This part cross-references GM 12135198 and Bosch-style relay reference GRTRY604 for the same application.

Common Issues This Relay Can Address

• Intermittent operation in relay-controlled body circuits
• No-start or no-function conditions caused by a failed switching relay
• Inoperative comfort package functions tied to relay control
• Electrical switching faults in 12V 5-pin relay sockets
• Relay chatter, sticking, or contact wear in high-use circuits

Installation Notes and Tips

Verify the relay socket layout, pin count, and contact type before installation. Confirm the vehicle uses a 12V 5-pin changeover contact relay and compare the original part number against the interchange references when possible. Always inspect the relay cavity for corrosion, heat damage, or loose terminals before installing the replacement.

For fitment verification, match the vehicle year, make, model, and relay function to the application data. This is especially important on Chevrolet Silverado, GMC Sierra, and Cadillac CTS platforms where multiple relay variants may exist.

Quality Assurance

Hella is a recognized automotive electrical brand with broad OE and aftermarket coverage. The 933332601 relay is built to operate across a wide temperature range and to meet the electrical demands of common 12V relay applications.
