Re: Shifting problems,how to fix
I am not understanding... what happens when you just put it in drive? It is an automatic, right? Why do you put it in first and then shift into second?
the transmission should be a computer controlled trans.
Have you checked your trans fluid level? If it's very low you may be running it out of fluid.
you should have your vehicle scanned. See if there are any trans codes. Scan the trans to see what the pressures are and what is happening when you drive it.
If it works in first gear, can you get it going up fast enough to put it into drive and skip second? Don't over rev the engine but get it up to a speed that third gear would drive at. If the trans continues after that then second gear may be gone. Need a trans rebuild.

2003 Buick Rendezvous over heating
I replaced my thermostat several months ago due to it over heating. Then, about a month ago, i topped off my radiator fluid, and forgot to put on the cap, resulting in all my fluid escaping and over heating my car. i added fluids and the worked fine, no over heating issues. Howeer, it the temp guage would never go above cool. So, i replaced the tstat again, thinking this was the issue. Now my car seems to want to over heat. goes all the war to 3/4 hot. What do i do now?

Fan stopped blowing and climate control display went black
2002 buick rendezvous cxl - just had starter done last week and yesterday had alternator done. Changed a high beam bulb last night and right after when I started the vehicle & turned the heat on, the climate control display went black and the fan quit blowing. Checked inside fuses 30, 26, 39, and 41, they are good. Not sure if related, but today the wipers quit during mid wipe. It's a snow storm here and can't drive my vehicle without the heater working and now without wipers. Any ideas are greatly appreciated!

Buick intermittant high idle and car accelerates on its own
I'm getting these symptoms second hand for a 2002 Le sabre Limited. It will do 45-50mph on hiwy without touching accelerator. I've been told accelerator is not showing any depression when driving and butterfly no open in park. Then put in neutral rpm's come down then put back in drive and it repeats. This wasn't as bad to start then got progressively worse and now constant. When in park idle ranges up and down 1200-2000 rpm's. All these symptoms occur with the cruise and A/C on or off.
Check engine light has never lit up. No codes. All sensors have been monitored with normal readings.
Throttle body has been off and cleaned. MAF, IAC, TPS, MAP, PVC all changed. Plunnem was checked for cracks when T-body off. Ether sprayed all over engine with no change in idle and no vacuum leaks can be found.
Cranks and starts normal. Does not miss or hesitate. Any Ideas?

Re: 2010 Buick Lacrosse electronic mystery
there is a rubber bot over the wire harness that goes from the door to the body. Moving the boot out of the body opening and pushing it into the door to expose the harness is one way to see if there are broken wires without damaging the boot.

radio will not shut off
I have a 2010 buick LaCrosse. When I turn the ignition off the radio and dash lights remain on for at least 10 minutes. Sometimes the radio turns off and the dash lights stay on. Can this be reset so that the radio and lights turn off when I exit the car? Thanks, Ron

Buick Century idling eratically
Hi car experts, I'm hoping you can help me fix my car. Below is a description of my problem, and things I have already tried--thanks, Beth.
My well maintained 1998 Buick Century, with 160k miles, is idling funny, but only when warmed up. If I start the car when it is cold, starts fine, runs great. If I start the car when it is already warmed up, like after filling up with gas, then it might not start on the first try. And once it does start easily, or may start and die, and once I get it started the idle goes way up and down. I've tried to fix it myself as I don't have a lot of money, and would like the car to keep running for a few more years. After reading, and trying lots, I came to the conclusion, since it runs so well at other times, that it might not be a serious problem, but a sensor that is giving the car bad info. I read to unplug sensors one at a time to figure out which one might be bad. When I unplug the MAF sensor, the problem goes away--I felt pretty proud that I had figured out what ails the car. I bought a new MAF, installed it, but the problem is still there. Aside from the MAF being bad out of the box, what might be my real issue? Could another sensor or problem be hidden when I unplug the MAF?
What I've tried:
Car has good compression. I tried what I saw on youtube, and sprayed carb cleaner on all the hoses while it was running, to check for vacuum leaks, this did not change the idle speed, and visually, despite their age, they all look good. I have put in new spark plugs and wires. The check engine light is on, but the folks at Autozone say it is only the evap system--I tried a new fuel cap, that didn't make it go away. Could the evap system cause idle problems such as this? And if so, why does unplugging the MAF make the problem go away?
The only problem that exists with the MAF unpluged, is when I first put it in gear to drive, the car loses power when I go to step on the gas, but only the first one or two times, after that car runs totally fine--is this what the car should act like with the MAF unplugged? But if I plug in the MAF, the car doesn't lose power when I first step on the gas, but once heated up and I restart it, it does the crazy idle.
Any help or thoughts are appreciated,
Beth

95 Buick LeSabre Electrical Issue NEED HELP!
This is pertaining to an electrical/ignition problem for a 95 Buick LeSabre with 94k miles. The car battery is consistently dieing. I have 7 amps drawing from the battery when the car is turned off. The battery is brand new, I have replaced a replacement just to be sure I could eliminate the battery however it is the $80 battery from auto zone so theres a slight chance it could be the quality of the battery. I have taken it to my buddy to test parts on the car that draw power when the car is off to see what might be sucking the juice from the battery. The car will not be able to start 3 days after it was last turned off. The odd thing is the car started the past three straight days, I can it to recharge the battery and when I went out today to start it, the battery was dead. This is the first time any thing like this has happened to the car.
Do you have any suggestions on why this is happening? I’d be glad to answer any questions that would provide additional insight into my dilemma.
