1993 lumina i did a diagnostic test with the paper clip. the cooling fan turned on as soon as i put the clip in....normal? the fan wouldn't come on when the engine was hot and when i did the test it was cold! anyway... i got a code 33 & 35. any ideas?

It is normal for the cooling fan to remain on when the air conditioning is on. Turn the air conditioning system off and see if the fan continues. If so, check the fan relay.

it seems to be on the bottom left front of front of the intake right below the thermostat. Good luck for you!

Could be the temp sensor on the radiator or the fan relay. I wouldn't drive it to avoid overheating & damaging the engine.

break out some paper clips and try to fix it, but really i would just buy new car or not worry about it

also there is ebay(for the assembly(the replacement parts))

Bring the vehicle into a repair shop the technician has to duplicate the situation before he /she can conduct testing. I don't think your cooling fan is the problem . I'm leaning towards engine main relay.(located under the dash board) contacts getting hot and once you turn off car there is no ventilization inside the vehicle ( a/c air blowing on relay) to cool it down. The only
draft is coming from cooling fan to cool off its contacts. Pretty soon you'll have longer wait periods before you can start the vehicle . Unless you live in the Artics.lol

those fans can cost allot of money unless you get it used or off ebay or junkyard, I would first check the fuse and the cooling fan relay making sure its not faulty next also replace your temperature sensor, what it does it sense the temperature of your coolant in the engine and when it reach certain tempature it send information to the computer telling it to turn on the fan to cool down the engine down. its fairly cheap and it take 2 minute to replace; if the sensor is faulty the fan will not turn on automatically. next if you did everything and the fan still does not work You can pull the fan out and test it buy direct contact using some spare wire wires and touch it straight to the battery to the fans plug. it hard to believe both fans fail at the same time. keep in mind both fan work in sync, although the 2nd fan is only a back up help to cool the engine while AC is running.

A radiator fan is designed to pull air to pull air through the radiator to help cool it, while blowing the air on back across the engine to try to assist once again at keeping the unit running cool as to not over heat.

run hot even at highway speed? no leaks, or sweet smell? ever have to top off coolant? ever boils out of system? if no to all these, sounds like your cooling fans aren't working. there is a fuse either on the motor cradle or on the passanger side wheel well. start the car, let it warm up, and check for power to the cooling fans.

change intake gastets

change intake gaskets you will find it blown thats why your problem happens when your engine is warm the alum. intake warms up and expands opening the blown gasket
