Thank you B&M Automotive! They are Honest, Experienced, and affordable! The first place that I took it to said that I needed another motor and boy were they wrong. I'm glad that I found B&M and they were quick to let me know that I did not need another motor. They knew exactly what it was and had it fixed in no time. I highly recommend them!

Had an electrical problem with my F-150 (parasiticdrain). Battery would die every 2 days. They traced the problem and at a great price! They know what they are doing.
