I had the dash cluster changed due to a recall

I had the dash cluster changed due to a recall. Now the interior lights stay on. Dodge wants nothing to do with this but they did say it's the dash cluster that's causing it.Y would it they just replaced it. So now im looking to c where the door jam switches are and long behold none to be seen. Are they inside the doors? And what do u suggest.I did go back to dodge and ask them if there was an interior light relay they said yup and sold it to me but yet they can't tell me where it is nore can I find it.I also looked through the entire Haynes repair manual and nothing about a relay. Im stumped can u help me jason. Ps there are hundreds of people having the same problem and dodge turns away at the problem. If I wasn't down on my luck do to the storm sandy I would be able to bring it somewhere to get looked at. I lost just about everything. Can u please help. God bless you and your families
