Hello ,
Here to answer automotive questions and make you feel comfortable and become familiar with your product.

For this type of repair/diagnosis it will very helpful if you can get the module scanned and list the fault codes. If you need to go to autozone or pepboys they have low cost or free services.

Let me know when you have them and list them here for me to evaluate
