Direct Replacement Amplifier

This professionally remanufactured OEM temperature control amplifier carries part number 27760 1LA0A and is built specifically for the 2011 Infiniti QX56. It integrates the air-conditioner control function into a single unit. The module arrives with no unlock code required and has been cleaned, serviced and verified to 100% working order.

Straightforward Swap With One Critical Check

Installation is a direct plug-in replacement when the existing unit bears the exact part number 27760 1LA0A or the listed compatible numbers 284B11LA0B and 284B11LA0A. The most common issue is ordering by appearance alone; units that look identical and share the same connectors can carry different data streams and will not code to the vehicle. Verifying the part number on the original module or confirming with a VIN lookup before purchase prevents a non-functional fit.

Owners Needing An Exact OEM Match

This amplifier suits QX56 owners who have confirmed their vehicle uses part number 27760 1LA0A and want a professionally remanufactured unit that restores factory climate-control operation without additional programming. Buyers who cannot locate that exact part number on their current module, or whose vehicles use an external amplifier architecture, should not purchase this unit as it will not function in those configurations.
