The fan on my Camaro is not working without the ac on.It is a single fan system. I posted earlier and was told to replace the sensor, today I ran into this problem. I checked on the passenger side head today and found a plug where you say the sensor goes( no sensor brass plug that looks factory). I tried to run down wires to where the sensor should be and only found one unplugged wire, the only problem is that the bundle only contains one wire. The plug end looks nothing like the plug on the sensor.
Could the previous owner have cut the wire and plug off and if so does any one have a pic or wiring diagram for that area and what the wires should look like[like origin of the wiring that goes to that sensor, routing of wires and possible a good place to get more wire and a replacement plug ( junkyards around this area usually cut all wires that go to the engine when pulling the engine out)]
Any other suggestions are very welcome also.
It is getting warm in Georgia and I need my fan.
Thanks Jody

It is possible that the previous owner removed the sensor. If this is the case you need to go buy one and the pigtail socket for the sensor. When you do DONT GET THE ORIGINAL ONE IT CALL FOR! This won't turn on the fan untill about 238 degrees. What you need to get is Borg Warner # TFS4. (I am a manager at an auto parts store) This will turn on the fan at about 225 degrees. The connector plug if it is removed is part # PT 770. This is the pigtail that hooks the wire to the switch. let me know if you have any questions
