Cooling fan test

[byron366]

Hey everyone,

Its my first time posting, and I hope to get some help. Anyways, the A/C stopped on my car in June of 2009, and I am thinking of repairing it. Anyways that's not the thing. I always used to hear the fans come on when the A/C was functional. I already know it had something to do with lowering the pressure through the condenser. Ever since then, I have never heard the fans that I can remember. I just want to know what pins to jump on the low and high speed fan relays in the underhood fuse box, so I can test that it is still functioning. And also a few questions about this. Do i connect the wire while the engine is running? will i get shocked if using gloves? And finally, will the car start if both relays are disconnected. Hopefully that isn't too much to answer.
Thanks

And by the way, its a 98' Mystique 2.5L ATX.

First off..I would check the 60amp engine bay fuse (for the fans) first before you do anything. If good then jump away..

with keys off....Pull out the 2 relays (green is low and black is high) and use a jumper wire on the 2 large pins in the fuse box for the low speed fan relay. I believe the pins are parallel to each other. If the low doesn't go on then it might be the resistor. Yes you can get shocked, so be careful.

I had a similar problem and found out that my resistor was shot. This is found in the drivers side lower part of the fan shroud facing the radiator. I believe to remove it you'll need 7mm or 8mm and prolly easier from the bottom.
