Can't find anyone to program these tire pressure control valves. Been to 3 Ford dealerships, discount tires and many car dealerships in the last 2+ years. Save money and buy beer for a month, better results! Disappointed in Dorman. They've changed the ad since I bought mine. Now they say you need a programmer that sells for an extra $200. A 2012 Ford Escape with 80,000 miles Michelin tires installed so I'll be watching that flashing light for a few more years.
