Resistance checks are really worthless in most automotive applications. A correct way of diagnosing a problem is using voltage drop tests. Measure from after the load on any circuit to the negative terminal of the battery. Any voltage over a couple tenths shows a possible issue on the ground side. A DMM does not load a circuit and does not provide any real valuable information.
