I looked on your site and I was not really seeing exactly what my problem is.  I am a woman with little mechanical skills, how ever I can do somethings...  My problem is:  My Buick's battery went dead on a Sunday and was jump started, and then 2 days later the battery died again and I was jump started and I went to advanced auto parts and they put in  a new battery. (they did the cord plug to the inside to keep the electronics from going haywire.)  But later that day, when I turned on my ac the vents are not working properly... I have air blowing out of the defrost and I have air blowing in the back seats... but I am unable to get air into my front vents.,.  I noticed reading blogs people had similar problems but they also had other issues and I am not sure what could be wrong.  I Googled and did see that other people who had Rainier's and their batteries went dead, their vents in front did not work either.. there were no solutions...  Can this be a fuse that needs to be replaced or is it the actuator  that you mention in other peoples blogs. 

What do you  think , and if you did have an idea, can you give me step by step or direct me to a step by step ??  I really do not have a lot of money to spend it on a mechanic... 

I would appreciate any help that you could give me.

Thank you again,

Rhoda 

Hi Rhoda,

Your problem should be the same as the one in the repair article that I have included a link for. The exceptions would be if your Rainier is a 2002 model of if you have adjustable pedals in your vehicle.

I  have a 1999 Buick Century, and every time  I turn on my AC or heater it makes this loud squealing noise. What could be the problem and how cheap is it to fix?!

Thank you.

Hi Krista,

Assuming that the squealing noise is coming from under the passenger side of the dash, I would say your blower motor needs to be replaced. I have included a couple of links that relate to your repair although they do not show how to replace the blower motor itself. The costs can vary quite a bit depending on quality of parts used and if you are replacing yourself or having some one do it for you. In my own shop the whole job would run about $250 + tax, using an original equipment blower motor.

1999 Buick Century Heater-A/C Blower Inop

Tina asked: I have a 1999 Buick Century with auto a/c. The heater and air conditioner blower would leak water from the passenger side vent, but only leaked 3 or 4 times before the blower completely stopped working. Now the blower will not work at all. What could be the problem and how do I fix it? I can hear a clicking sound when turning on the heater and I can feel warm air coming from the vents. Could this be a resistor and which one if it is?
