Engine Cooling problem
1994 Buick Roadmaster V8 Two Wheel Drive Automatic 120k miles
Primary fan does not come on, but works when plugged in to secondary side. Secondary fan comes on when a/c is on, but car still runs hot in warm weather. Thermostat replaced last year. Relays checked out OK. Am told I need to replace the pcm.
Is this the next logical step and, if so, where on the vehicle is it located?
