can faulty a/c condenser fan make car overheat without ever having turned on a/c

did it overheat prior to the repair?? if so, how many times?? get a leak down test to confirm a blown head gasket.

Both fans are supposed to run together with or without A/C.

Do you mean engine has more than one thermostat? This is news to me.

Do you have coolant losses issues?

These fans are NOT wired to run simultaneously. One of them is a radiator cooling fan and the other is an A/C condenser fan and are prompted to run differently

Please check the wiring schematics.

I did, They are triggered independently

Circuit is independent but they work together.

They wouldn't be independently controlled if that were the case.

This is what Mitchell1 says.

DESCRIPTION & OPERATION

The electric cooling fans are used for radiator and A/C condenser cooling. Cooling fans operate when A/C is on and when engine coolant temperature exceeds a specific value. One or more cooling fan relays may be used. Radiator and condenser fan motors are controlled by the Engine Control Module (ECM) based on engine temperature input and A/C system status.

Nothing in that description states that they run simultaneously all the time. The PCM has in dependent controls so it is able to control them independently. I'm not saying that there is never a scenario that runs both of them but they have their own independent criteria to run and they may or may not run together at any given time.

I don't know maybe the vehicles over your place has a different system but the Tiburon we have here have both fans running when A/C is turned on or when temperature increases.

yesterday I drove for about an hour using the a/c for the first time this year and the car overheated,so i turned it off "the a/c " and still the overheating persisted.Even at highway speeds 70 to 80 mph.So I let the car cool down and tried again with no a/c usage this time and same problem.I replaced one thermostat and apparently there's another one behind that one with another gasket so I will have to do that again.Hope this helps How do you jump the a/c fan from the battery to see if it works maybe Ineed that extra cooling power

and no there was no other overheating problem before yesterday

If the car overheated at highway speeds, then the fans are not your problem. You need to pressure test the cooling system to determine where any leaks are.
