The multifunction switch is usually the culprit when both faill together. They can get pricey but you get what you pay for and it is at least two hours of labor or more to replace so don't buy a no name brand switch. The best place to get great prices on OEM replacement and get parts from quality remanufactered and new switches is www.rockauto.com. Try them out and see what they have. As they are a closeout retailer you will find that the stock changes quickly and you might find a new deal that was not available days before. So, check it often as new part lots are available at different times and the good deals go fast.
