P0300 is a random multiple misfire. Could need plugs and wires or a new coil pack. Take it to a qualified mechanic and have them test it.

SOURCE: buick century 2000 wipers

I found the following description on the web, this covers a bunch of the questions I was going to ask...

I own a 2000 Silo and wondered the same thing and do see some GM vans with this problem.

When I bought mine I also bought the Haynes Repair manual (1997 thru 2001 all models GM) #38036 to learn how to fix this and a LOT of other components in/on the van.

For $20 it's worth it.

To answer your question: If the wipers stop at the position they're in when the switch is turned off (Fail to park), disconnect the multi-function switch electrical connector. (This is located under the dash next to the firewall and steering column)

If the wipers now park, replace the multi-function switch. If the wipers still do NOT park, check the wiring from the wiper motor to the switch for a short circuit. If the circuits are good, replace the wiper motor.

Note: There are other adjustments needed for proper operation than just bolting and new motor on.

You can have a look at this manual at any automotive parts supply store.

SOURCE: how to replace a coolant level sensor, 2000 buick century

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

The cabin air filter for your 2002 Buick Century is located under the cowl in the firewall between the engine compartment and the passenger side of the front seat. To change the filter:
1. Leave the wipers in up position.
2. Open the hood
3. Remove the weather stripping from passenger side of cowl
4. Unclip the window washer line (two or three places)
5. Remove the three fasteners with an ordinary screwdriver (one is easy, the other two were more difficult)
6. Take out the cowel cover
7. Remove old filter
8. Put in new filter
9. Replace cover, fasteners, washer line, and weather stripping.

Do it about every 20,000 km. I left mine for nearly 130,000 km and it was filthy dirty.
New filter costs about $12

SOURCE: odometer light out on buick century not working

Sadly no, there is no fuse or bulb to replace. You either have to send the instrument cluster out for repair or replace it with a new unit from the dealer. You could also obtain a serviceable one from a salvage yard. Most shops should be able to replace the instrument cluster or advise who can repair it.

2000 Buick century custom only has heat when you accelerate fast but puts out cold air when you accelerate normally or at a steady speed.


Check your coolant level. Not enough fluid in the radiator to circulate when the engine is operating normally.
