#473 of 592 1994 Buick Century Transmission
Aug 27, 2009 (1:56 pm)
Hello! I own a 1994 Buick Century Special with the 3.1L V-6 engine! The car has been a great one for me & has 85,000 original miles! Here, just recently the motor has to warm up before it will go into any gear! Fluid has been changed once in its lifetime & is not low! After the warm up, the car still runs like a brand new one! Any ideas, hints or suggestions would be greatly appreciated as to what is causing this!

I have the same problem, its not the fuse and the hayes book is useless.
the windows go up very slowly and then stop and you have to wait 5 minutes until the motor cools before they work again, NO buick dealer could fix it.
I was told to try and replace the power motors and see if it fixes it?

Rebuilding a 2000 Century.
I've got 200k+ miles on the car, 8 years as a Pizza delivery at night and Real Estate Property Management during the day car. The exact mileage is in question as the PRNDL cluster went down a few years back.
There are wiring, relay, sensor and module issues throughout. I installed high intensity blue white head lights in '02 which caused wiring damage throughout and 9 years of rain into the passenger floor board from a bad seal at either the heater or in car cabin filter, possibly could be a blocked drain in or around the firewall. The water leak has led to a nice rusty fuse panel in the passenger side access panel.
She has the standard Century issues: Kicks into gear because of a bad solenoid in the tranny, oil in the radiator, already replaced one window register, body control module causes door locks and side mirrors to work only intermittently, A/C doesn't work, blown fan motor and blower control module, right side radiator fan only works off a direct jump from battery to white electric wire, left side radiator fan does not work at all even with direct power from battery, rear speakers work about 10 days out each year, need new headliner, carpet liner and arm rest console. Where to begin?
Recent repairs: new brakes, rotors, tires, tie rods, front wheel hubs, rear sway bar, drivers window register, plugs and plug wires, 1 & 4 cylinder coil, engine temp coolant sensor, serpentine belt
Seems like a money pit, should I trade her in on a good used Regal or keep dumping man hours and cash into her?
#477 of 592 Rocker Panel rust out
Nov 07, 2009 (10:19 pm)
I have a 2001 Buick Century with 46,000 miles who's rocker panels have rusted out.
Since the rocker panel is considered to be a structural member the whole side panel right up to the roof panel must be replaced.
??How in the world can GM sell a car that rusts out a structural member that quickly get past a recall??
My 96 Buick LeSabre has 178,000 + miles on it and it still is not rusted, much less rusted out. Fantastic car. Low maintenance costs, Great ride, Economical.
Granted I put on the best tires available, but that car handles slippery roads as if they were dry. ABS system still works perfectly in spite on Minnesota salted roads. Love that car.
??Anyone out there have another fix for those rusted out rocker panels??

My buick is giving me alot of problems. It has probably about 220000. The previous owners only drove it highway back n forth to work and they were older so you know they didnt dog the car. I have had it since June of this year and most recently since it has gotten colder it has gave me tons of problems. This is what happens the most. I will start it up and take off. The heat will sometimes get hot but after about a minute and extreme heat it will turn cold and the temp will go all the way up to the red but not go into the red. When i pull over and and put it in park i can rev up my engine and if i keep doing that then it will get hot again but that doesnt last it will go right back to cold. i have no idea what is going on. i had someone change the thermostat but that didnt work. i dont know what to do.

Had a similar problem on a another car. Sounds like you have air in the cooling system. Some cars have a bleed screw usually on top of the themostat housing but could be elsewhere. I would thouroughly flush the system with prestone super flush. Backwashing would be better. Refill and find out any special way of bleeding out air.
Check also that there is no coolant in oil(milky looking) or oil in coolant. Suggests a blown head gasket. A compression leak down test would also show a problem. A check of water pump would also be a good idea. Have you recently used any sort of stop leak in the radiator? This stuff is notorious for blocking off internal cooling passages. Got to flush it out of there. Best of Luck...
#480 of 592 96 century w/ unknown coolant leak
Dec 12, 2009 (5:23 pm)
Have a 96 Century that is leaking coolant. 99,000 miles. replaced a squeaky water pump but that didn't stop the leak. All hoses and radiator appear fine as well as no heater core leaks and all coolant seems to be leaking on the belt side of the engine. I'm hoping its not an Intake manifold gasket leak but can tell where its leaking from. It also seems to be worse one day then not as bad the next. going through about 1 to 2 bottles of antifreeze a week. Any ideas? Was told to try a sealant made by K&W.?

Believe me, it is the head gasket. Pretty common problem. Been there, done that.

nothing in a bottle is going to save you on this one I'm afraid. You should have the cooling system pressure tested to identify the problem for certain, but odds are it's the intake manifold, yes. Maybe you'll get lucky, hope so.
