I'm having a huge problem my car 2008 equinox is causing me a head scratcher. My radiator fan isnt engaging when the temperature raises and the engine starts to over heat. I've replaced the temperature sensor replaced the relay checked all the wiring on the fans they are good. Everything seems in order I had to result to rigging the relay to stay open while i drive so the fan always runs so it doesn't overheat, so I'm plugging and unplugging the relay whenever I drive. This car has been nothing but a headache since I bought it. Ive read and tried so many things and I'm at a lose. I need any and all ideas please!!!!
