2003 Galant - Service Engine Light On

About 2 weeks ago the AC evaporator drain was clogged, so I had to pull the battery and battery tray out to clean the drain. Yesterday my son noticed that the service engine light came on and is now staying on. Could this be the result of removing the battery from the car. The car seems to be running fine. Any ideas

2003 Mitsubishi Galant Heater Core Valve Hello everybody!

I am new to this forum. (sorry, I couldn't find a way to post a new message - hence I am replying to this posted message).

I have a question regarding my 2003 Mitsubishi Galant. How difficult is it to replace the Heater core valve in this model car? Please help me if you know how to fix it.

Thanks a lot!
