$24.99
(You save)
Restore the electrical link to your A/C compressor clutch with the Standard Ignition A/C Compressor Wiring Harness / HVAC Clutch Coil Connector (MPN S-648). This connector carries current to the compressor clutch coil that engages and disengages the compressor, and it installs as a direct-fit replacement across a broad list of applications including the 1993 AM General Hummer, 1978-1986 Audi 5000, 1962-1990 Buick LeSabre, 1962-1989 Cadillac DeVille, and 1967-1989 Chevrolet Camaro — see the Buyer's Guide tab for the full list of 164 applications.
Job it does: provides the electrical connection between the vehicle wiring and the A/C compressor clutch coil.
Direct-fit replacement: a plug-in service part for the listed applications, so you replace only the connector rather than splicing.
Signs it may need replacing: a cracked, melted, corroded, or broken connector that keeps the compressor clutch from receiving power.
If a damaged connector is the cause of an A/C clutch that will not engage, this replaces it and restores the circuit; diagnose the cause before replacing, since a no-cool complaint can have other electrical or refrigerant causes.

Frequently Asked Questions
What does this part do?
It is the wiring connector that carries current to the A/C compressor clutch coil, which engages and disengages the compressor. It replaces a damaged connector rather than the compressor itself.
Is this the compressor or just the connector?
This is the wiring harness/clutch coil connector only — a pigtail that supplies the electrical connection to the compressor clutch coil. It is not the A/C compressor.
Will installing this fix my A/C?
If a cracked, melted, or corroded connector is why the compressor clutch is not getting power, this restores that connection. A no-cool issue can have other causes, so diagnose first.
Which vehicles does it fit?
It fits 164 applications, including the 1993 AM General Hummer, 1978-1986 Audi 5000, 1962-1990 Buick LeSabre, and 1967-1989 Chevrolet Camaro. See the Buyer's Guide tab for the full list.
What numbers does this connector interchange with?
It cross-references 88862248, PT198, 457, EC109, 12101907, and 5606. The manufacturer part number is S-648.
