Can anyone explain this to me?
I don't like using auto all the time becuase it uses the compressor and eats more gas.
I may just be shooting in the dark, as I don't have an ECON setting and don't know exactly what happens when it'* engaged, but if the compressor'* off in ECON mode, it may well be that the fan that cools the A/C condenser coils is off too; but since that fan also blows on half of the radiator, your coolant temperature goes up. In normal A/C mode, that fan'* on, cooling the condenser *and* the radiator, so coolant temperature goes down.
Just a guess, though.
