Good afternoon and welcome to JustAnswer!!

The first thing you will need to do is check and see what codes are in the TIPM which is the fuse box under the hood. You will not be able to get these codes with a cheap code reader so you will need a scantool, once you have the codes post them here so I can tell you how to repair it..

Talk soon,

Thanks for that but there are no codes as stated. Figured there would be no help here. Please just cancel this trial and refund whatever was charged thanks

I attached a screenshot of the WITech we use that will be needed to retrieve the codes from all the modules to determine your issues.

Since I haven't got a reply I'm guessing you have it fixed....

Glad I could help and thank you for the positive rating,
