Just bought the car it has very low mileage. I took the scroud off the engine to see if I could tell where noise is coming from - hard to tell - but seems like it is more from the back 3 cylinders or around there somewhere. engine is the 3.8 L - noise always goes away after it warms up.
Battery dies in a few hours 1 time, might last days the next time. Replaced battery, failed load test. Replaced starter, excessive draw while cranking.Replaced radio, had a internal short causing it to stay powered up on occasion. I have isolated it to the rear fuse box under the seat by the battery.
how to replace the dash light Buick Lucerne 2006?
The car has remote start so there is a brake in the wires that come from switch on the hood latch. It gives me hood open all the time therefor I can never put the alarm on. I have replaced the hood latch assy to no avail. I need to know where the 3 wires go so I can replace them. A wirering diagram would be helpful.
2000 Buick Lucerne where is the crank shaft sensor located
I got in the car and hit #1 seat set up button to put my seat in set position. It did not work. I realized I had left an inside light on and turned it off. The car cranked fine, but once on the highway, messages came up on dashboard with engine symbol lit up, service stabilitrak and service traction device. Also noticed at stop sign that it felt like a mild pull back of motor or jerk.
