I just bought this Escort and within 24 hours Check Engine light came on it was Coolant Temp noot making it through fuel loop. Ok fine I figure water pump or thermostat or the sensor. Now it was blowing heat until last night now it just makes a clicking noise when I turn on the heat on high no blowing of any kind I even tried the AC but again nothing. Please help. I like this little car.

 

Welcome to the site..

The click is most likely the blower motor relay..
On the blower motor connector, as a test,, probe/add a ground to the Blue/Black wire. The blower should run full speed, if not, could be a bad relay/contact.. If it runs, next step would be a look at the blower resistor (thermal protectors fail, but not all fan speeds are affected) or possibly the control panel..
