Smile The same fan relay question

I've search and read

I havent test the fan with aligator clippers to the battery.
The relays are good.
The fan doesnt turn when the ac is on, and doesnt blow cold air.
The fan turns on when the engine is warm.


Today I let it idle for a while until the fan came on.
I drove the car and sprinted it down the street doing 35mph with and with out the A/C on.

When I pulled in, and lifted the hood, i think the fan stopped, and there was a burning smell and light smoke coming from the back around the O2 sensor area.

Any Ideas? While i search online tonight? Thank you.

On my 2003 the fan will not turn on until it has reached full operating temperature, 200F, or until the AC is turned on. If the fan is not coming on when you turn the AC on then mostly likely a relay or fan issue. Since you state the relays are good then I would think the fan is the problem.

Is there any oil on the exhaust that could be burning off? Could be where your smoke is coming from.

Hmmm, i didnt check. I looked around the gasket and no oil. I know water always drips more than a regular car from the exhaust pipe. Plus there is an oil leak from the pan, but its not enough where it shows on the dip stick. Ill test the fan tomorrow or tuesday.

I would suggest checking the engine coolant overflow tank. Make sure it's not cracked and leaking. Also check that the hose going to it is not leaking.

Smile Re: The same fan relay question

fan test.
I connected the alligator clips to a 9V battery.
The 3 Ping part of the fan I connected one of the black wires to the middle ground, and the red one to the right pin. It turned.
Then I took it to the left pin, and it didn't.
I would assume is means the low speed fan isn't working?
And I would need to purchase a new fan?

I would hook it up to a 12V source. If it functions the same when hooked to a 12V source then I would replace the fan.

9 volt battery? Where did you get the information that a 9 volt battery is the right voltage to manually check the radiator fan?

When I jumpered the pins to the fan relay socket, I was measuring 10-15 Amps. That's why the fuses are 20 Amps and if you want to manually energize the fan with an internal switch, it should be a 20 amp switch with 12 gauge wire. Actually, you can simply energize the relay with a 1 amp switch and 22 gauge wire. A 9 Volt battery will not run the fan motor.

Some where online lol. It turns the fan though. If it turns it, then it should be ok, right????

Cool Re: The same fan relay question

I tested the fan with a 9v Battery. The fans turn on all the pins. Slow, but they turn.

I previously said the fan didnt work, because I picked up a fan that was in wayyyyyyyyyy better shape than mine, and it only turned on one pin test. So of course if the good looking new fan was not working, no way my rust one would. WELL IT DOES!

I'm in the hood now. Maybe the wires werent tight, or would I need a new fan relay fuse?

I noticed in the junk yard, there was a fuse box that had big black box shaped fuses. Is that location of fuses underneath the regular box of fuses???

brb...I will use a better battery to check as well back Yep. I used the car battery, same thing.

Any suggestions? I received a Camshaft sensor code, and I purchased a temp thermostat and camshaft sensor. Should I replace that and check the fuses. I dont get any cold air from the ac after charge, and the fan doesnt turn on when I start the car and have the ac on.
