Also some fans are reversible, might they be spinning backwards ? that's my $0.02............ good luck, let us know howya makeout........E.

As previously stated no.
And I'm with 91parkave, my old black car did the same thing, when the temp was 85+ and the ac was in sitting in traffic the temp gauge would just climb up but as soon as you started moving it dropped right down. Only one of my fans was kicking in.
