How long will the check engine light stay lit after changing the radiator fan relay?

Question

2003 Dodge Caravan 3.3L, how long will the check engine light stay lit after changing the radiator fan relay?

Answer 1

You probably have to clear the code. You could try clearing the code by disconnecting the car battery for about 30 minutes. If the light comes back, then the relay didn't fixed the problem or you may have other problems.
