1998 Honda CRV

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.

I have no idea what it could be. Please. Help!

Hi doreen3123,

Do you mean when heater is turned on, both radiator and condenser fan works?

When AC is turned ON, does the compressor clutch clicks in?

When fans are working, temp still shows a high reading?

Do you have coolant losses issues?

Was bleeding of cooling system performed when repairs were carried out?
