Temperature gauge issue
My son bought a 2005 Pontiac Montana,
the temperature gauge is (sprung or
wrapped) the veh does not and according
to the previous owner, never has had a
temp issue. The previous owner said the
batt was dead so he jumped the veh, when
the gauge failed or sprung? If it helps
trouble shoot the horn doesn't work either.
My son located the horn relay and fuse.
Fuse is good. Not sure how to check the
relay. Could jumping the veh effect the
temp gauge? Any ideas?
