What is climate control ECU?
Environmental Control Units (ECUs) are similar to Portable HVAC (also called portable climate control) but differ in that ECUs are typically engineered for military applications. That means that ECUs need to meet military requirements and they need to be able to stand-up to military environments and conditions.
How does the climate control work on a Mercury Grand Marquis?
Trigger the test by setting ignition to ON, turning climate control device OFF, pressing FLOOR + OFF, then pressing AUTOMATIC within 2 seconds. 888 code means all tests passed. Codes 24 and 25 are common errors for blower motor issues. These codes might show if the engine is not running even if there is no issue.

Autocar LLC. Filter your results by entering your Year, Make, Model to ensure you find the parts that fit your vehicle. The climate control module, also known as a temperature, A/C or heater control module, adjusts your heating and air conditioning to keep your cabin heated and cooled.
What to do if your climate control unit leaks?
These are usually a case of a vacuum leak where the vacuum harness is not tight to the back of the control head. Two 10″ twist ties holding the vacuum harness tight to the control head should fix it. You can replace the vacuum harness for $20, but I would still install the twist ties. The would feed through the back if the unit.
Why does my PCM fail every time I replace it?
PCMs typically fail for one of two reasons: voltage overloads (often due to a short in a solenoid or actuator circuit) or environmental factors (corrosion, thermal stress or vibration). If the shorted solenoid or actuator isn’t found and repaired, the voltage overload it creates may damage the replacement PCM, too.
