Where would the ignition module be located on a 2004 impala ls. Cant seem to find it?

not sure but if u know someone that works at a car/auto body shop u can ask them to type in their computer the name and year of the part u need to find where it can be ordered well at least in my city.

If your talking about the Ignition Control Module!It is under your coil packs.( what your coils sit on!) Location: Top of engine,right of the alternator.
