2001 Buick Century Limited air conditioning situation

Vehicle has the dual control A/C system - 3.1L engine - recently the A/C has been blowing ice cold air on the driver side and warm/hot air on the passenger side (makes no difference if the dual control is ON or OFF)
Tried disconnecting battery to reset A/C system - no change
Checked all fuses in both (interior and under hood) boxes - none blown
Have tried changing settings from AUTO to all different manual combos with dual controls in both positions - no change

2001 Buick Century Limited speedometer problem, Speedometer not working but odomitor ok. Is there a fuse?


if the odometer is working then the problem is with the speedometer head unit as the odometer gets its information from the same source as the speedometer. you can have the speedometer head checked and fixed if its fixable.

My heater or defrost will not blow warm or hot air, it only blows cold air. My temperature gauge is running in normal operating range.


there are two hoses running to the heater radiator from the engine cooling system , one has a inline tap that controls the flow of hot water to the heater , check the tap is open , may be the control cable is not opening the tap , or it frozen and must be replaced.

2000 Buick Century- RPMS significantly rise and


You may have developed a vacuum leak that the idle air controller is trying to compensate for. Or, it could also be caused by a dirty mass air flow sensor. You need to post the engine type and the other conditions the symptoms occur. It's hard to diagnose a problem on such limited information. Conditions such as engine temperature, foot on brake, in or out of gear are extremely important factors to take into consideration when solving engine performance problems.

I have a 2001 Century Buick and my low coolant light keeps coming on, although I have coolant in my tank. I have also changed the sensor recently. What could be the problem?


Hi!!
You may have air in the system. There should be a bleeding valve on top of the thermostat housing, where the upper radiator hose connects to the engine. Look in your owner's manual for the procedure to bleed air from your cooling system.
As long as the temp. gauge shows normal readings, you should not worry about any damage to the engine. Once the system has been bled, take the vehicle to an AutoZone or similar auto parts store to get the Low Coolant light reset, or, wait until it resets itself.
Good Luck! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!
