2003 Buick Rendezvous CX Fwd 4dr SUV (3.4L 6cyl 4A)
Went on a cross-country family trip
and encountered problems; The service
engine light stayed on after it was
serviced and the fuel gauge and low
fuel indicator light stayed on when
the tank was full. The lighter and
auxillary outlet fuse burned out.
OnStar wasnt working either until we
took the car to a Buick dealer to find
these two outlets are on the same fuse
as OnStar! Water collected on the
floorboard in heavy amounts after
rainfall. We came home from our trip
to our dealer to find we had a leak
around the air conditioning unit They
said it was a bad seal around the
unit. We had water damage and
corrosion to the electrical system.
Check seals in the engine and find
a way to water proof the
computer/electrical system connections.
