Alternator ba ang problema?

Possible or one of the rectifier is busted. Hook up a volt-meter to check voltage drop.

May whining sound ba as you rev or the steering becomes hard?

yes steering becomes hard... at bakit direct yung fan nya ag on yung susi mag on na yung radiator Fan nya..

Hard steering(EPS) and whining noise is a tell-tale sign of busted alternator/ rectifier.

For 2nd issue, could be a tampered fan wiring. If not tampered, a shorted thermo switch/ AC senser.

iirc coolant sensor and thermo switch are separate bung screwed on different location in the engine.

saan mismo yung location sir ang thermo sw? o sundan ko nalang yung wire ng fan?

Try ko check pero makikita rin yan ng electrician na titingin ng alternator mo. Same lang nman ng 2nz yang 1nz.

Yun wire ng fan sa relay nkkabit so yung primary ng relay i-trace mo ,o kung saan tampered malamang sa acc-on position kinabit.

Clean the Throttle body and MAF sensor. That should help, of not fix it.
