For some reason my fans only will come on if i turn my a/c on or if i turn on my manual switch.

I am looking for the instructions for the manual cooling fan how to. I remember blacknblack or soemthing like that had a really good how to.

I just need to go over what i have my fan keep quit working by pcm controll and this is getting old.
 


Re: cooling fan manual switch

Its probably your ect sensor, its a dual sensor so your gauge will probably still work. If you havent checked that already, that is. You can view the coolant temp PID with the scan tool.
 
Re: cooling fan manual switch

Yea i think its is my coolent sensor. someone has my scan tool.... but i have had this issue for years. My fans only come on if i turn the a/c on. I unpluged the sensor and my fans still do not come on.
 


replaced the temp sensor under the intake manifold. my cooling fans still do not turn on. Except on low when i turn the a/c on.


I tested the relays they test good to. I even swaped out my pcm for another.
 


Stock PCM? If the computer's seeing the correct ECT, it's not a sensor problem. I assume the GP's the same as the Regal in that the HVAC control just reports to the PCM for AC, so if the fans are turning on with the AC, it's not the wiring there, either.
