Your dealer or bone yard is your best bet on it.

Is the wiring harness bad or missing? Or how bad?

If it is not to bad a lot of times it can be repaired.

i went to the dealer and it cost $1,112 and in the junk yard i bought 1 but it was the wrong one wasted 250 for nothin the part number is 12159183
