Or if button pushed nothing at all would happen. While the heater works, it emits a death rattle before blowing air. My AC doesn't work at all and was told that I would need to replace the compressor. The most dangerous and expensive repair has been replacing the front differential mounting and wheel baring. I was told that it was only mounted on one side and was leaking and this was a common problem with this model car. …”

“Early this morning was driving on the freeway in our 2004 Lincoln Aviator. There was a moderate rain fall and zero natural light was available.

Unable to see, I drove off the road and was horrified to discover that I almost ran into the guard rail. While this situation did not result in any damage or fatalities, this could have easily been a disaster resulting in multiple deaths. …”
