well i just took my caddy out for a drive today and it was about 13 degrees farenheit here and i'm fed up with my 1991 sedan deville. One the two front doors were frozen shut can't get them open even after i was done driving it. two, my windows fog up like a little b*tch even with the darn defrost on. i don't know what to do anymore really. its got 165,xxx miles on the clock runs awesome still but i'm just getting fed up with these doings. anyone got any advice?
