Since the fan is electrically operated it is not the problem.it seems like more of a waterflow problem:the faster the engine turns-the more the water pump turns.i am only guessing but it seems like it could be low on antifreeze or your water pump is failing..good luck

My 1993 Buick Century's heater and defroster will not blow hot air. Also, there is water on the floorboard on the passenger side. The car is not running hot. What is wrong?


There could be a number of issues at work here. First, and most important is to address the source of the wet floorboard on the passenger side. Get you fingers wet and then rub your fingers together. Does the wetness feel a bit more slippery than just water? Smell it. Does it have a bit of a sweet smell? If so, this could be coolant leaking from the heater core into the passenger compartment. Slow leaks will take a while to notice in the coolant level. If this is the case, replacement of the heater core will be necessary. The wetness could also be just rainwater coming in from an open firewall plug, damaged door seal, or perhaps windshield seal, where rust or a poorly installed replacement could result in leakage. Now about the heat. First, is the engine coolant reaching operating temperature? Run the vehicle for at least ten minutes. Then feel the upper and lower radiator hoses. Both should be hot. If not, you may have a thermostat issue that is keeping the coolant from getting warm enough to produce sufficient heat. If the hoses are hot, then check both the supply and return heater hoses to the heater core. They should both be hot as well. If not, then a clogged heater core is usually the culprit. You may be able to get lucky and back flush the core, but most times replacement is required. If everything to this point has checked out OK, then it is likely that the blend door in the heater control box is inoperative and will not divert the cabin air through the heater core. This is hard to determine as it is all under the dashboard and sometimes difficult, if not impossible to see. Check the control head vacuum lines for cracks and breaks. Look at the vacuum actuators and ensure they are operating and that their linkages are connected as move freely. Repair or replace any problems found.

I have a 2002 Buick Century and my heater will blow air but only heats air occasionally.


If you know where the heater hoses are, lift the hood after car has warmed up I mean the engine running for at least five minutes, feel the heater hoses, if they are warm or hot and still no heat from the heater, you have an in line proiblem. if hoses remain cold, replace the thermostat with a winter thermostat.

Imy 98 buick is overheating the water comes out from the pasenger side inside da car..right under the glove box


That is where your Heater core is located. Its like a little radiater that your vents blow thru to get hot air for heating your interior. If thats leaking, its not gunna stop. Take this car in right away before you run your coolent dry and trash your car.

Heater on 2003 Buick Century only works when the rpms are up


Your likely problem is low coolant level. Check to make certain that your coolant level is topped up in the radiator and that coolant is also in the reservoir at the appropraite level as shown when on container when the engine is hot or cold. When the coolant is low, you have to have higher RPMs to get the coolant to pump through the system and heater core.
