Hi
I have a 1.6 16v Astra Artic. Recently the engine has been getting hot in standing traffic. I assumed this was an issue with the fan. I therefore removed the plug from the sensor on the back of the radiator and used a paperclip to connect two terminals. When doing this, the fan spins literally about once and then stops and will not turn again, no matter how much I wiggle the clip. The plug is of the two pin type, so I assume single speed fan. I then removed the cooling fan and bench tested it and it works fine. I assume that this must be some kind of electrical fault rather than a temperature sensor issue given that it only spins once? I'm not great with electrics (but keen to learn). I have access to a multimeter and have the wiring diagrams in the Haynes manual. I was just wondering if anyone had any general pointers for diagnosing the issue, can think of anything else I may have missed or whether there are any common issues that may cause this. Thanks in advance Mark
