Location of ECM on 2004 Buick Rainier?
Codes are saying I need to replace the ECM, I've got it ordered, but the parts
place need the number off of the old one. I don't know where to look.
It's a 4.2 engine.
It is probably on the passenger side either behind the glove box or behind the kick panel. A silver metal box with some wires running to it.
It may also be under the air cleaner box in the engine compartment. HTH. -Jim
Found it, it's on the side of the engine, on driver's side. In case someone else needs the information.
