SOURCE: How do you jump start A battery on the 2007 buick

Very simple.

First hook up Positive Red and Negative Black terminals to the battery in the known good car. Then hook the Red terminal on the opposite end of the jumper cables to the positive Red terminal of the battery in the known bad car. Then, carefully, without shorting out the connectors, connect the final black jumper cable to the 'frame' of the known bad car.

Hope this helps.

SOURCE: My 2007 Buick Lucerne drivers

first purchase the door handle assembly then remove the door panel. make sure the window is up and reach in and disconnect the rods making a note of which one goes to which one. unbolt the door handle and remove. the new door handle may come with a new rubber seal for it. position over new handle and reinstall. make sure to search the door panel for hidden screws holding it on before you pop the clips.. hope this helps

2006 Buick Lucerne Air condition going hot air could it be a bad fuse or relay if so how can I tell if a relay is bad

There could be a freon leak which would stop the compressor clutch from coming on. If the inside fan comes on and it blows thru the correct vents then I'd suspect a low charge of freon .

I replaced the transmission in a 2006 buick lucerne. no problem until I went to start the car . no start no communicaion with computer

Quite likely the on-board ECM needs telling the transmission has been changed or there is a fault in the new transmission.

It probably needs dedicated diagnostic equipment.

Why did the passenger side of the dual climate control on my Buick Lucerne only start blowing cold air? Have no heat on that side, just air conditioning works.

May b a blend door issue..
If its electronic unit then maybe a actuator gone bad
If controlled by vacuum then a broken/loose hose
Does that side change from different settings(dash/floor/defrost even)= blend door issue usually

2007 buick lucerne fuse for dash warning beep

If you are driving with a faulty oil pressure switch then how do you know when there is no oil pressure. Switching of the alarm will not fix the problem and oil pressure sender units are available at ant auto parts shop or dealer spares. Why wait a week when the job can be done in 10 minutes by any mechanic.

I have a 1992 buick roadmaster..and after driving my car for a while,the fuse to the ecm blows..what could be the problem?

Early 90's GMs have had more than thier share of electrical problems. the problem with your Buick is not unheard of. The most common cause of the ECM fuse blowing is a short to ground in one of the ECM sensor circuits. So check all of the engine sensor connections and the sensors. Pay particular attention to wiring underneath the car. Could be the ECM is faulty, but fairly uncommon for this to be the case.
