My sons 2003 Jeep Wrangler just started having this problem where the AC won't turn off. I've read on here that sometimes people have this problem even when the vehicle is turned off. This is not the case with his. It is just when it is turned on, you cannot turn the AC/Heat unit off. Help!

 

FYI this is the JK Forum, your son's Wrangler is a TJ if it's a 2003. Someone might know the solution here but you will have better luck on a forum dedicated to TJs or maybe the wrangler forum.
