Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

On your model here your vehicle uses signals from the TIPM ( integrated power control module which is part of the under hood fuse panel itself).This TIPM can be common to fail internally electronically and causes no light issues like you see or odd lighting issues.I suspect with what you have described here the TIPM has to be replaced to resolve this fault.It has to be programmed and usually by a dealer once it is replaced in order for it to work properly.
