If you have one on your dashboard, it overheats during a heatwave and stops working, unplug it, take it in and put it in the bottom of your fridge for a few hours. A friend of mine did that last Summer. He decided if it didn’t work it had “died”. He put it back in his vehicle the next day and it worked. The last I heard it is still working. He thought he would have to buy a new one before Christmas 2014.
