Hello, my name is***** will be helping you out! I have over thirteen year of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

The first step to do, it to verify there is no oil leaking or another fluid type leaking. (usually oil leak will cause smoke and odors as if there is something burnt)

Next step, is to take it to a certified repair facility to verify that there is no amperage overdraw from relays or fuse circuits. (Usually a fuse will blow before a wiring harness begin to short out & acquires a serious short thus, causing a fire)

Last step, look at a TSB that I have provided and see if it appears to be what you are experiencing. If it does appear to be your problem, then you would need to deodorize the vehicle using this procedure.

Let me know if this helps you :).
