stock temp gauge doesnt work for some reason.Aftermarket gauge was installed by previous owner.Cooling fans do not turn on at any temperature so in order for me to cool my temperature down and i have turn on my AC then both of my fans come on. I have replaced 2 sensors recently and it had no affect. The 2 sensors I replaced were right next to eachother. 2 pin sensor and a single wire sensor. Both near the thermostat housing. Someone was saying there might be a fan switch relay and others say there's something wrong with my ecu. Any ideas on what i should try next? Running my AC all the time is killing my gas. Oh, someone else said if my gauge isnt working or a sensor, my ecu thinks im always running cold which in return is making my car run the wrong air fuel mixture so I am always running to rich. Unsure about that one. Any help would be appreciated thanks
