Afternoon all Would very much appreciate some of that superb assistance again. Just had the thermostat changed in my car as the car just wasnt getting hot enough. Prior to this I changed the temp sender and when this didnt resolve it decided to get the stat changed too. So the mechanic has just called to say he has replaced the stat but everytime the car gets up to around 66 degrees the fans kick in for 10 seconds and drops the temp back down again and they are coming on about every 30 seconds. We are a little stumped anybody have any ideas ? Thanks again in advance.
