How much should and engine replacement cost? If i already have the engine? Labor cost.

Is this a problem with the control arm itself [internal switch] or a fuse or wiring problem


this has been the case since I bought the car used 7/10.
the light comes on and stays on, when I park the car after 20 minutes use it smells hot, but the temperature reads cool and the coolant is cool enough to stick your finger in it and the oil hasn't changed color, darkened oil would indicate a coolant failure. after sitting for just a minute turned off, the light stays off for another 20 minutes.

why will the front lights not turn on when the car is on. we checked the battery and it was good. all the fuses are good also. the light switch was also good.
