Need schematic for location of ECM on 2002 Chev Silverado 5.3L GAS ENGINE

It isn't a fusible item, it is a function of the Engine Control Module. You need an auto electrician for issues and to diagnose faults.

Enter vehicle info year , make , model and engine . Under system click on HVAC , under subsystem HVAC controls . Click the search button , then the second blue link is the one you want ! This system is pretty complex , pushing the A/C on button sends a request signal to the BCM - body control module , then the BCM sends a request message to the ECM - engine control module over the GMLAN serial data bus. Which then energizes the A/C clutch relay ! Hooking up a factory scan tool is the best way to trouble shoot this. Using the scan tool you would be able to see if the request signal is getting to the ECM an to see if the the ECM is controlling the clutch relay .

Attached are the diagrams requested - good luck!

For one i dont need your vin its a z24 which means it has a 2.4l engine it does not have an ECM it has a PCM powertrain control module, which is located for your car in the right rear corner topside of your engine bay, in 1995-2001 it is located inside the right front fender. I hope this info helps...

Well i searched this link all got was this information hope it helps you :
