My temp gauge has started reading higher than normal usually it is maybe a about a quarter of the way up,the last week or so it has been up over halfway,at first I thought it was just the extremely hot days but even with the temp dropping off it still reads high the fan is running and the oil/coolant levels are good and the motor doesnt feel really hot,any suggestions on what to check. Thanks

The thermostat is new but not o.e.m, I will look up the resistor.The blower has always worked just fine until now,its weird.Could I have aproblem with the heater core.

My 92 loyale wagon will not heat up and the blower will not kick on until the car has been running for 15-20 minutes.When it finally does it is just cold air,any thoughts or advice would be mucho obliged!
