    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

can this be done by myself or do I need to take in to shop and have done? What is time on this type of job?

 

Expert:  Jay replied 5 years ago.
HelloCustomer if you take it to a shop they shouldn't charge you more than an hour but yes it is easy and I think you should probably find in not difficult to do yourself. Please reply if you have any more questions, thanks.
Customer: replied 5 years ago.

I am a female and I am not sure about wires.

 

Expert:  Jay replied 5 years ago.
I don't think I can fix that for you, but the wires are connected to connectors so it is just a procedure of disconnecting the connectors and plugging them back in . If you don't feel comfortable you could ask a male friend to take a look or take it to a shop if your willing to pay the hour labour.

I hear that this is a dealer item and I have to order the complete piece not just switch. Why is that?
Expert:  Jay replied 5 years ago.
Hi, yeah you are right about that, but now I'm wondering do you just mean the knob that you turn in a circular motion?
