• Avoid "shop hopping" between different auto repairs shop in order to avoid getting the same repair twice.
• 2004 Ford Explorer XLT: Sometimes when I'm driving 65 mph or faster, my overdrive light automatically goes on. Why does it do this?

• 2001 Ford Crown Victoria: Why do my windshield wipers stop straight up when I turn them off?
• Where is a good auto repair shop in Ahwatukee?
• 1994 Pontiac Trans Am: Why won't the car turn over when I start it even though my battery is fine?
• 2006 Dodge Charger: My car shows the check engine light with no code.
• Is over-filling or topping off at the pump bad for my car?
• 1998 Ford Ranger: The airbag light is on in my truck even though I've checked it out and there doesn't seem to be a problem. How can I reset this?
• 1999 Lexus RX300: The dome light only turns on manually but it won't auto dim when the doors open and close.
