The vehicles are once again giving us fits. Maybe the fact that our rigs have 180,000+ and 240,000+ miles on them could be a factor. I don't know, but Christmas time is not the time you want to be spending money on them. Fortunately for us, Todd is very good at figuring things out. In this past week he has replaced the rotor, brakes, and calipers on the Blazer, the rotor and brakes on my Dodge Caravan, and figured out why the Dodge plow truck decided not to drive faster than 15 mph.
