Engine Cooling problem
1998 Honda CRV 4 cyl All Wheel Drive Automatic 147500 miles
My CRV temperture gauge goes up with the AC on. I shut it off, turn on the heat on high. Did not work. Had thermostat replaced, full tune up with radiator flush, and replaced fan starter switch. The same thing still happens. When the ac is on, fan on radiator does not work, when heat is on, fan works.
