Buick Park Avenue Electrical / Lighting Problems

I have a 98 Park Ave and the power windows have developed a problem of not working on warm or hot days. When the temperatures cool down the windows work fine, but when the air heats up they stop working. I don't know if this is a motor problem or in the actual power switch in the door. Has anyone else experienced this problem? I'm hoping it's something I can fix. I already asked a Buick repairman and was only told they could fix it for $500, and that is for only one window. If anyone can offer a more economical solution please advise me.

    Hi, since you mention "windows" as plural I would have to assume that it's not any one motor or switch. I'd look for the power source or ground. It's going to have to be something in common with all the windows. Have you checked the fuse or breaker connections? If you aren't electrically inclined you could be in for quite a challenge.

  • After I start my car a "reminder" chime,more like constant dinging that starts sounding off and It does not stop untill you turn the car off. Is there a fuse that I can take out so that I dont have to listen to that anymore untill I can get it somewhere to get it looked at?

    The front lights a very easy process. 1 Lift hood get a tork socket set loosen the two black knurled bolts. The whole wrap around unit comes out where you can see
    the side light the low beam high beam and running light just twist counter clockwise
    and pop out old lamp pop in new. The side marker are accessed the same way
    from reaching hand underneath fender twisting the bulb holder then pop out and pop in. The rear Brake lights are accessed from trunk area. Remove the two cargo cleats, then unscrew two phelps screws either side of trunk latch then the right side cargo cleat the entire plastic splash piece comes out after plastic screws are levered out. 10 mm socket removes the nuts the whole brake light and turn signal comes off and again twist the bulb unit and pop out old bulb pop in new. To access the backup and license bulbs remove the gray cloth again levering plastic screws. Then remove the eight 10mm nuts the whole trunk lid light assembly can be removed and bulbs replaced and reassenbled.

    The turn signal mechanisum on my girl friend's 1978 Buick Park Avenue was broken by a repair facility that tried to fix it. Now the left signal will not latch and when you turn on the right signal the horn blows and no signal. They also lost the shift indicator from the dash so we have to guess what gear we are in. The garage says they can't find any parts and have washed their hands of the problem. Needless to say we don't go there any more. It was her parent's car and she insists on keeping it. It look great and runs like a top.

    Where can I find a source for the part? I have not pulled the steering wheel but I suspect that the plastic switch is broken. I may have to replace the wiring harness or perhaps the complete column. I'll do whatever it takes. Just imagine this tiny lady sticking her arm out of this BIG Buick's window to make hand signal. Most young drivers today don't even know what she is trying to do. They think she's trying to flick out a cigarette.

    What models and years would have the same parts so that I might do a junk yard search? We are in the Central Virginia area but I guess UPS can bring in a part from anywhere. Thanks for any help or leads to solve this problem.

  • On my 94 PA (not Ultra), the service department prices a replacement for the Overhead Lighting Monitor Module--displayed below the rearview mirror--at $535(!) Rather than shell out for this outrage, I told them to disconnect it as they suspect it is draining the battery. It flashes constantly when the car is being driven but does not light up when ignition is off. :(

    The battery was new in the summer of 2007 and connections appear clean. First, is the diagnosis likely correct? Second, I'm told it will cost $400 just to disconnect this module as it is positioned deep under the dashboard. This sounds suspicious to me but what do I know? If I go ahead with this, should the battery stay charged? :confuse:
  • I have 2003 Park Ave with auto climate control. The temp display is dim enough to be almost impossible to read. I assume bulb replacement needed. How difficult to access bulb? Do I need to take to dealer?

    Some of the temp displays go dim. It's not a bulb. I believe there's someone on Ebay rebuilding them. I recall with a Regal back in the 90s there were some where you take them apart and resolder the black, rectangular resistor blocks and they worked right again.

    I did a search on Ebay and came up with this store. You might email and ask about rebuilt Park Avenue units
    AC control and speedometer rebuild

    Or you can search for price on gmpartsdirect.com or rockauto.com for the AC control unit.

    Second Imidazol97's reply. There are some bad solder joints on the resistors inside that climate control unit. If you are handy with a soldering iron or know someone who is, it is a cheap fix (cost of a little solder) and an hour or two of easy labor for the do-it-yourselfer. After you disassemble the control unit, you can try to wiggle the resistors on the board and it will be pretty easy to see which ones have bad solder joints. If you aren't familiar with soldering and resistors, one of those rebuilt units will fit the bill as it isn't a bulb problem.

    I have a 1994 park avenue. The horns goes off without anybody in the car. All I have to do to stop it is hit the horn a few times. Seems llike it is sticking in the column when you press down on the horn. What is the remedy for this problem? Could it possibly be some moisture in the column? This car had a leak in it a few months ago, but has been repaired.
  • imidazol97imidazol97 Crossroads of America: I70 & I75Posts: 17,717
    Quick guess. If it went off while you were driving I'd think it was a wire that was touching occasionally and had worn through its insulation. But because it's while the car is parked, I suspect it's in the contact pad in the steering wheel. A few cars ahd that problem long ago; the cold would make the plastic change and the contact would cause the horn to blow.

    Because you have an airbag in the steering wheel that complicates the matter. You might try touching around on the pad to see if you can find a sensitive spot that might be making contact when it shouldn't.

    Thanks for your reply. It makes sense what you said because the horn mainly goes off when the sun hits the steering column in the middle of the day. I will get someone to look into it. Thanks again.

    I don't recall the year, but check the NHSTA site for comments about that. Look for comments on the web. Ask the Buick dealer service manager if it"s been a problem and there"s been a recall>

    I now have 153,000 miles on my Park Avenue. I was driving at freeway speed with my cell phone charger on, the radio and the A/C. I started to see smoke come from below the steering wheel. I tturned everything off pulled over it stopped. I continued driving with nothing on but it started to smoke again but I did not notice a burning smell. the smoke was similar to when you blow out a candle. I checked all fuses to make sure that they all were the correct amperage , and they are. I have checked for grounds as well. I am concerned that my air bag may deploy while I am driving.

    Has anyone had a similar problem and do you have a solution.
  • We have a 1997 Park Ave and it runs great for 165000 miles. One day my husband was at work on a lunch break listening to music with the air running and the driver seat back. He said all of a sudden everything stopped working but the car was still running fine. Now the radio is out, the tail lights are out (we cant drive at night, which sucks) the dash lights are out, the driver seat is permantly stuck in the lounge position, and the interior lights are out. Everything else runs great. My husband checked all the fuses and none of them are blown, the only thing he thinks it may be is the computer chip. Has anybody else had this issue or what do any of you think it may be?! :cry:
  • SOME YEARS AGO I HAD A CADILLAC THAT HAD SIMILAR PROBLEM.
    ON LEFT HAND BOTTOM UNDERDASH, THERE IS A PANEL NEXT TO PARKING BRAKE, THE DEALER TOLD ME THIS, REMOVE THE PANEL AND THERE WAS A BIG ELECTRICAL PLUG, SOMEHOW IT HAD MANAGED TO LOOSEN, I JUST MOVED IT AROUND RESETTING IT AND ALL WAS FINE.
    YOU PROBABLY HAVE SAME PROBLEM, NOW TO LOCATE YOUR PLUG, THAT'S THE QUESTION, AND I DO NOW KNOW, IT MAY BE IN SAME LOCATION, SHOULD BE EASY ENOUGH TO LOOK IN THAT PANEL, LEFT SIDE NEXT TO PARKING BRAKE. HOPE THIS HELPS

    I have not worked on 97 ParkAvenue but assuming it's setup somewhat like my 03 leSabre, there are different computer boxes that control different parts of the car.

    First you need to check every fuse with a continuity tester. They can look okay but be blown. I am assuming you have a fuse block under the hood and one under the rear seat with the battery.

    Also tighten grounds on the fuse block under the rear seat. Check the owner's manual to see if there are fuses in another location.

    My opinion is it's likely a fuse or wire connection that burned.

    I'd look for a factory service manual from Helminc.com for the car if you want to try to see what boxes control those items. The factory service manuals sometimes are for sale on eBay by searching for service manual and 1997 buick or use words Park Avenue instead of buick. Check carefully for ones offered to be sure you get all two or three books. Compare pictures of ones offered. You want the ones from Helm, which are the ones you get if you order from the page in the glove box owners manual that came with the car. Original price is around $135. They are available at the website--that may include shipping.

  • Buick Regal NO START electricial problem,Car stoped running. All lights flash,buzzers buzz,no start. After 10 min car started, ran for 1 min now wont turn over and all lights on dash flash and buzz. PLEASE ANY HELP.
  • bowfanbowfan Posts: 55
    Without hands on examination of your car, my first guess would be a failure of your upper intake manifold plenum. This is assuming you have the Series 2 3800 engine, non-supercharged model. When mine failed, symptoms sounded like yours.

    Do you have any coolant in the plastic antifreeze recovery tank on the fender? If no, this points to a leak somewhere in the cooling system.

    Are you your own mechanic?

    If yes, pull all your spark plugs and then watch the engine while someone attempts to turn it over. When you pull the plugs, you may find some cylinders full of fluid which will start to spill out. If it turns over and is full of fluid, it will spray anyone standing in front. :P

    If this is your failure, what happens is engine coolant (antifreeze & water) will flow into your lower intake manifold (thru a crack in the upper plenum) and from there down into your cylinders. Air and fuel vapor will compress in a healthy engine. Water & antifreeze won't. This causes a condition called hydrolock. In a worst case scenario, it could cause expensive engine repair or replacement as piston rods and parts get bent or broken. But it is a common problem, and easily fixed for the do-it-yourselfer. I have never personally seen any parts bend or break.

    With the engine locks up, the starter seems to get jammed up, hence the flashing dash lights as it tries to draw a huge electrical load on your system but is unable to turn the engine over. I've had to pull the starter and put it back in to free mine up.

    This is just my wild guess based upon your brief description. It may be something simple like a bad starter or battery. Or something simpler.

    If you are your own mechanic, you can fix it for less than $150 in half a day. Plus oil and coolant change.

    Pull the plugs and let us know how it goes. :)

    If you are not your own mechanic, how well do you know your mechanic?
