- Oct 15, 2004Wow, That about covers it I guess!
Both Paul and Joel had very sound advice.
I have been meaning to check the main grounds, as my AC blew a fuse
last summer. I have also been meaning to repalce all the fuses, and
sand the turmanals. I will check the pumps also, may just replace
the one in the tank, as I supose it is a pain to get to, and if I'm
in there to check it anyway, might as well start out fresh.
I don't think I will go as far as getting a new car though, as the
car is a very nice town car, and performance is not what I am looking
for for my 16 year old daughter. She is high mantinance enough!
