• [COMPARE BEFORE ORDERING] 39794-SDA-A03 appears in limited catalog Q&A as a check-against number for a specific 2007 TL-S A/C relay case, but it is not treated here as a full replacement chain. If your old relay shows 39794-SDA-A03 or a different terminal pattern, confirm by VIN, socket layout, circuit function and catalog fit before purchase.
• [INSTALLATION NOTES] Disconnect the battery when required by the vehicle manual. Pull the old relay straight out; do not pry hard against the fuse box. Inspect the socket for heat damage, corrosion, moisture or loose terminals. Install only into the same 4-pin Micro ISO relay cavity after matching terminal count, terminal layout and circuit label.
• [SYMPTOM GUIDE] May help restore a controlled circuit only when diagnosis confirms relay failure. Relay-related symptoms can include intermittent circuit operation, no-click/clicking behavior, overheated housing or corroded terminals. This relay will not repair a failed motor, compressor, fan, wiring harness, fuse, switch, sensor or control module.
• [VISIBLE MARKING CHECK] The sample housing shows 7001 and 4J09 markings, but visible face codes can vary by production batch. Use 7001 / 4J09 as a visual check aid only; the final fit check should be part number, 4-pin layout, relay box diagram and removed relay cavity.
