cooling fan help again.

[slver 3800]

ok so i got a 2000 camaro 3.8l auto. i did a coolant flush and chagne this weekend and while doing so my father and i noticed that my fans werent working. anyways i went ahead and changed the 3 fan relays and check both the 40 amp and 10 amp fuses both of which were fine. well today i went and tested the terminals on the fans and got nothing. my father said he thinks it might be the thermostat for the fans that went. however neither of us know exsactly were to locate it and dont want to strip all the wiring to find it. anyone have any idea were it is located.

Before you determine that anything is actually wrong, what did you do to test the fans?

I dont know what the stock fan settings are for 2000, but my 96' was set to kick on the low fans at 225. If you take a test light and clip it to something metal like usual then bump the relay terminal it should kick on when grounded. You probably just need a tune or a manual fan switch.

yea i tested both the high and low fan terminals with a test light got nothing. i checked both when the car was cold and hot got nothing.

If you turn your A/C on the low fans should get on. One way to test them.

The fans have have a switched ground, not power.

You can attempt the manual fan switch write up I have, but admin might wake up from his cv6 coma and tell you how wrong it is.

Re: cooling fan help again.

i turned the a/c on and the low fan comes on. but i have yet to see the high fan or low fan go on while the a/c is off. any ideas?

My idea is that you're just paranoid. If your car isn't overheating when you're driving don't worry about it. If it is, then sure look into the fans as being a possible problem. Otherwise, don't worry.
