Time to  pull out the refrigerator and clean it up?  Did the dust we drove
through  contribute to this failure?  We did not have dust inside the van,
but I  suppose it could get into the refrigerator through the  flu.

if you do pull it, i would also install a small CPU type electric fan back
there.. air circulation helps with cooling and prevents moisture buildup
which  could lead to drivers side seam rust.
