Buick Cars & Trucks - Recent Questions, Troubleshooting & Support


As far as I know there isn't one and I've never seen one in all the repairs I've made on these cars. You have to just visually follow the actual metal brake lines from the wheels to the ABS controller and back to the master. Odds are unless you have an actual fluid leak in one of these lines that you have a different issue if you are having a brake problem.

You have to remove the base first by pushing with your knee about a foot from each wall, and pull up quickly. That releases the spring locks and pull the base out. You'll then see the bottom of the seat back and see a couple of fasteners, one on each side. Remove them and push the seat back upwards and the seat back is loose.

White smoke is either steam or a huge quantity of unburned fuel, both of which is a potentially serious fault and in the case of petrol or gas can be dangerous, less so with diesel.

Steam is caused by coolant ingress via head gasket, cracked head, block or sometimes by an intake manifold or gasket.

Large quantities of unburned fuel likely to be an injector stuck wide open.

I strongly suggest you don't attempt to drive it and ask an experienced person to take a look.

This is a very complicated system with 6 fuses, a turn signal module and a dash integrated control module. No way you can figure this out without a pro grade wiring diagram.

Firing order is usually found on an inlet or exhaust manifold. Take off dizzy cap and turn the engine to identify rotation direction then from #1 follow the sequence.

Yes you can. There is a thick cable going to the starter motor and a thin wire. All you have to do is short those two together to activate the starter motor.

Turn it off with a switch, when light stays off your system is working properly, when the light stays on, there is a malfunction and has to be checked out.

Most are the pins around, near handle could be screwed and caps like light look for them.

Ok, The other day I had a "service Engine Soon" light. The car was shifting really hard, and slamming into each gear. I have found that if I pull over, take my code reader and plug it in, I get a PO742 code. Torque converter circuit stuck on. I proceed to erase that code from the computer, and restart the car and it will run and drive totally fine, as if nothing is wrong. I have been doing it this way for 3 years and the car is running fine to this day. It hasn't cost me a dime in repairs, and I commute 500 miles/week. It's worth a try, because I have heard that if you spend 800-900 bucks to get it "fixed", the problem WILL return some day.

i just came across this problem myself the other day. i have a 91 buick park avenue that sometimes won't start. i checked several things out like cable connections and coil pack etc. etc. come to find out it was the wiring that came off the coil pack and connects to the crank sensor. the wiring that ran over top of the water pump had finally heated up so bad the coating on the wires had melted and when the engine got hot enough the wires would come in contact and send false signals to the computer not letting it start. after the car cools down and the wires contract it would start. so check the wires from the coil pack to the crank sensor to make sure the wires are not melted together.
