FAQ

Is this relay compatible with my Chevy Silverado?

Yes, the 15328864 relay is a direct replacement for the OEM part used in Chevrolet Silverado models equipped with the standard A/C compressor control circuit.

What does “normally open” contact type mean?

A normally open (NO) contact remains open until the relay coil is energized, at which point it closes to allow current flow, ideal for controlling the compressor.

Can I use this relay in a 24V system?

No, this relay is designed for 12V DC operation only. Using it in a 24V system could damage the coil and affect performance.

How do I verify the relay is functioning correctly after installation?

Check for proper voltage at the coil terminals and ensure the compressor engages when the A/C is turned on. A multimeter can confirm contact closure when the relay is energized.

Is the relay covered by a warranty?

Jerwickeli offers a one‑year limited warranty covering defects in materials and workmanship for this relay.
