Anyone actually have to get their ECM replaced?  My mechanic was saying that when he tapped it all the electrical issues I had went away..I can get a plug and play ECM preprogrammed for under $100..I don't want to replace it if not needed..I've rarely heard of an ECM going out..Anyone else?

They can go bad.

They take alot of abuse.

But before you replace it I would suggest removing and cleaning the connectors and grounds.

What are your symptoms?

That's what I mentioned...I agree,the connections need to be checked and cleaned..Tap it to make it work sounds more like a connection thing.ECM's rarely go out..But,If I need one,I know where to get it.

Got to remember we are dealin' with aging electronic parts that are shaken and beat on with every use of the vehicle.

Broken soder joints are most common.

I still gotta tear apart my old climate control unit to eyeball a failure of the LED readouts.

But it still will control the HVAC actions/doors/fan so keep it for a emergency!
