General Maintenance & Repairs - Fans not working

If im not mistake when you turn the A/C on one of your fans are suspose to come on correct??? Mine are not comeing on at all. Well i have checked the fuses, they seem fine what about the relays??? anybody know how to check them??? I have swap them out with good ones from my truck and still not work . Also i did a cam install a couple of days ago and i was driving it the other night and stop and parked, soon after i noticed that i had coolant blowing out my over flow. Is there any relation with the 2 problems???? I dont know if i had enough Antifreeze mixed with the coolant might possibly had to much water, would that cause it to blow???

They may or may not be related. When you did your cam install did you maybe forget to plug in the fans? Did you bleed the air out of the system also?

On my car both low speed fans come on initially when turning the AC on, then high speed cycles on/off with temp. Strange it's puking fluid and not showing overheating on the gauge. Usually when that happens the fans are staying on even after the key is turned off for a couple minutes cause of high temp.

Yeah it's blown my mind. I checked the fans with a direct 12V source and they work. but dont either one come on with the A/C on. I did unplug my A/C compressor, A/C stopped working but that should bother it, OR should it ???

They may or may not be related. When you did your cam install did you maybe forget to plug in the fans? Did you bleed the air out of the system also?

As far as bleeding the air out, I filled it up and let the thermostat open a few times and topped it off as needed. Is that correct??

Is there 2 temp sensor on my car?? i know about the one in the driver side head, wheres the other if one, but that wouldn't be the problem for the fans not turning on with the A/C switch on would it??

Just one ECT sensor - if that was bad gauge would be inop or acting strange, throw a code, plus the car would run bad because the PCM uses the ECT input for several things. Sounds like you got all the air out, but check the level in the radiator with the car cool to be sure. Wouldn't hurt to make sure the sensor connection is tight too.

Yeah im still trying different things. Damn this has got me stumped

Don't know if this will help - www.gearchatter.com/viewtopic8947.php

Quick question. I forgot to mention cause i didnt think it mattered but i have the A/C compressor unplugged would that matter ???

Plugged the A/c back in no luck, I can jump the relay and fans come on but thats it. Someone plaese give some assistance
