"Jack" (1991 Buick Park Avenue)
The behavior is erratic. Sometime it starts with no problem.
Other times, even though the battery is fully charged, it will
not even turn the starter and displays the Security light on
the dash. The Buick dealer says it could be one of several
problems with the key lock/switch. However, they describe
it as expensive($200-300). Has anyone had this problem
and how was it fixed?
Clean the battery posts and cables, then post again if it
