The service shop I took my car to after it failed emissions due to some thing to do with the gas cap and the tank itself, says they need to drop the tank to get to the top where the parts are that need to be inspected. They say they have to drop the majority of the rear end to get the tank out. They $600 just to drop the tank. Is that accurate? The machine repair tech where I work says that is crazy, car manufacturers do not build cars with gas tanks that inaccessable since it is a system that needs repair often.
The main line fuse is located on the left side of the car, under the hood, and seems to be a part of a bar. What is this bar called and how do you replace this? My friend "Jerry rigged" it for now but I need to get it fixed as soon as possible. Will this be expensive to replace?
You know besides normal maintenance. I just bought car a few months ago. It has been well taken care of since new. Thanks! Oh yeah, the cruise control stopped working recently. I have not had it checked yet.
