    Just wondering if you ever found the cure for P401. I have changed the EGR, The Pipe to the Exhaust, The Map sensor, and a couple of other sensors that I am not sure what they are called. Help Please. :confuse:

    Sounds to me liker the bearings are going in the AC compressor.
    This is slowing your belt and causing associated electrical problems,
    the bearings ease up after a bit and problem slacks. Eventually the
    compressor bearings will seize and after a few minutes of engine
    running you'll have a complete engine failure: overheat, oil pressure
    power steering etc.

    Hi. The Temperature control on the dash operates a vacuum controlled door that mixes cold air with hot air. It is possible that yours has 2 doors. One may not be getting the vacuum to open or close the door. I'm not sure if yours might have 2 doors (1 left &1 right). That kinda would explain your problem though. Checking the vacuum on these "doors" might not be too easy. Definately requiring removal of under dash panels. Also a Vacuum Pump/Gauge would be helpful in determining weather the doors are operating correctly. Good Luck!
  • yes after a head gasket repair job. driving on freeway thought it was a wind gust until my speed was dropping. seemed like the harder i pushed on the gas peddlethe faster speed dropped. after stopping and restarting i could not go faster than 25 the more i tried to speed up the rumble seemed louder. so far i'm into 500;00in labor alone mechanics miffed. next step is timing belt or chain one mechanic thought 94 had fiber optic timing so ruled out any ideas out there new car maybe
  • ...on the driver's side when driving, but not when applying brakes? Please tell me this isn't going to cost me an arm and a leg. The sound sounds like it's coming from the driver's wheel area. It doesn't do it all the time either...that's what's weird.
  • i recently bought a 96 century with 50,000 miles. it starts and runs great with no serious damage. the car has stalled 4 seperate times and re-started within 5 mins. two of the four times. had it towed the other two times and it restarted normally 6-12 hours later. it seems to happen sporatically with no common traits. can anyone help. MUCH APPRECIATED!!!!!!!

    Hello,
    I have buick 2005.
    I have changed the oil after the 'change oil' message has appeared and the message still appears.

    How can I make it disappear?

    Thanks

  • The only solution I've heard of is the coolant named Descool. It has been taken off of the market and there are several lawsuits against them for ruining several vehicles. My brother is going through the EXACT same problem right now, and I have been racking my brain thinking about it. So far, this is the only thing I have come up with...Did you look at your water pump? I'm sure you did, but he said that he was hearing a gurgling after he shut it off coming from the coolant system. This I hope is the only thing wrong, the Descool coolant. Buick used it a lot. Was your check engine light blinking too?
  • has anyone else also experienced this problem with the pearcing whining?
  • I just had the same problem yesterday. The dealer wanted to charge $85 to turn it off. I took it to an Auto Parts store that we have in Ohio called AutoZone and they put it on their own handheld computer and cleared it for free. You might want to try that route. It couldn't hurt.
  • Im working on a '94 Buick century 3100 V6 and having trouble changing the head gaskets. Is there a How To article or video that could help or any tips that I could use. Im having trouble getting it apart, where are the bolts to take them apart? Any help will be appraicated.
  • Buick 2004 Century,sevice engine lite came on,put scanner on it,came up with P0480-cooling fan control circuit malfunction, what should I be looking for,wireing,relay or ?? Thanks :)

    Thank you all for you replies
  • I have a Buick Century 2003. After getting my oil changed at a quick oil change place, they told me to turn the ignition key to the on position (without starting the engine), and flooring the gas pedal 3 times in quick sucession. The oil change soon light then starting blinking and went off. Apparently, this reset the computer.

    Hope this works in your case.

    Hi everyone,

    One day a few weeks ago, all of my power windows on my 1988 Buick Century gave up working at once. This leads me to believe it's a fuse or circuit breaker issue but I'm unsure what to do next. The fuse diagrams I've found do not show a power window fuse that is accessible in the dash fuse box. The information I've found on the circuit breaker says that if the problem was overheating, that the breaker will reset itself. Does anyone have any leads on what I can try before bringing it in to have it looked at?

    Thanks in advance! :confuse:

    My 93 Buick century front windows will not go down, but for some reason the front ones go down. Tried changing the fuse but that wasn,t the problem. I wondering if I have to buy new window switches. If anyone knows answers please help.
