I just got back from a drive and noticed that my rad fan is continuing to run even after shutting it off. So I started to play with my fan switch (pos power to switch to fan, I also have the stock fan activation) and it would then turn off then back on. This went on for a minute or two then it runed off. I then had control of the fan with my switch again. Im confused? I have had this switch piggy backed on the car for a number of years without problems. I also noticed the other day that the coolant gauge (factory not aftermarket) dropped a bunch then slowely came back to normal. I picked up a thermostat but have yet to install it. Does this make scence to anyone?
