Buick Terraza Repair Questions
Question: 2005 Buick Terraza 6 cyl all wheel drive
Automatic 60,000 miles. Have you heard on any problems with the vehicle not
starting intermittently? My wife drives this vehicle daily, and at no certain
times, the vehicle will not turn over, or even "click" when turning the key. She
will continuously take the key in and out, and keep trying to start the vehicle.
The vehicle starts anywhere from 2-20 mins. later. I have had the vehicle in to
service centers, and they cannot find anything wrong. I have been told until
they can duplicate the problem, I am out of luck. This is really embarrassing to
her, especially when she has coworkers/friends in the vehicle. We recently went
out of state, and the vehicle did it again. We had a tow truck coming to help us
when it finally started. I have checked the batter, the connections and the
starter, and cannot find a "smoking" gun. Hopefully you have heard of this
condition.
Answer: Take it to your local dealership and
have them install a vehicle data recorder. Have them set it up to record theft
system data. This device can be set up to record in the event of a fault code or
manually triggered.
Question: 2005 Buick Terraza 6 cyl Two Wheel Drive
Automatic 40,000 miles. My van has recently developed a problem with the
passenger power door. The door will close but it seems will not latch at the
rear latch. It seems like the door isn't recognizing that it's closed. The motor
attempts to keep running even after the door is closed but the latch doesn't
catch. I can turn the power off to the door via the switch and close the door
manually and it will latch. Manually closing the door causes another problem
though. The door open alarm, beeping will continue to sound even though the door
is latched closed manually. The door ajar alarm will sound but there will be no
indication in the information section on the dash. I tested to see if the door
ajar works on that door when it's actually open and it does indicate on the
dash. I pulled the 40 amp fuse for the problem door thinking that it might stop
the door ajar alarm beeping and it didn't. The strange thing though is when I
did pull the fuse the door control box would start to click as though a relay
was buzzing. I went ahead and pulled both 40 amp fuses for left and right doors
thinking that would cut power to the door control box but the relay still was
fluttering. Is this a door control box problem, feedback switch problem, opening
motor problem or ???.
Answer: Sounds more like a problem with the
latch/switch assembly not seeing that the door is closed, and trying to run the
motor more and that would also explain the warning light, the BCM doesn't think
the door is shut because the latch isn't telling it so
Question: Hello all, my wife and I have a 2005
Buick Terraza with 60K miles and the problem we are having is this: When we turn
on the Heater, only the drivers far left vent blows hot air? The middle vents of
which there are two of them in the center dash, only the left middle blows warm
(not hot) air, the passengers blows cold as does the middle vent on the dash
closest to the passenger? Any thoughts on this? The A/C blows fine, just the
heater is split oddly in this fashion. Thank you in advance.
Answer:
You might want to have your dealership check to see if
you have the latest HVAC module programming. I know a new version was released
on Sept. 17,2007
