Default Check engine light after coolant flush.

Changed my oil and and flushed my coolant today. After 10 minutes of test driving my check engine light came on. Just wondering what it could be? Im going in to the shop tomorrow.

Yes, post the EXACT code(s) here for comment. Anything less is pure guesswork.

Note: I did spray my engine with water(Dumb,I know) after the coolant flush. What should I check for water?

None of this codes are a misfire code, but if that is how it's acting, look at the distributer and see if it is full of water. The codes that u have are for the hvac system. Make sure your jeep isn't overheating too. Just because the temp gauge is correct doesn't mean that it isn't getting hot

That's what my mechanic said. He couldn't figure out the problem. I'm bringing the jeep to the dealership on monday.
