Inside light will not turn off

Good morning.

What inside light?

Why did you have the plugs replaced?

I need as much information as you can give me to help you.

Roy

Because they needed to be changed and I gave it to my grandson and nothing was ever wrong with it and he changed the spark plugs because I never had it done. When he gave it back to me he said that he had to put another rear end on it and now the water thermostat is on inside of the car and we do not know happened.

I am not understanding what you mean with the water thermostat is on? Do you mean it is overheating?

Is the check engine light on? That is the yellow light for the engine control system?

Roy

No it is not.

Okay, again, what do you mean about the thermostat is on?

I am taking about it being on inside of the car.

I do not understand why it is on a.

Okay, slow down. What I need to understand is what you refer to as "it"?

I am trying to help but you need to help me by explaining what "it" is.

Can you take a picture and post it here?
