Air conditioning

Is the clutch on the compressor engaging? For it to be recharged, it had to be working. Check it to confirm. Lets look at this guide to help fix the problem.

it sounds like the compressor is not working

Thanks for this post I had this problem had to get a new compressor for $212.00 all fixed!

My air conditioner is no longer working. When I turn the knob, nothing happens. It does not make any noises nor does it blow any air at all. Can you provide insight as to what the problem could be and how much it could cost to repair it?

Thanks in Advance

That would be tough to do. I suggest you go to a shop for an estimate. The system is complex and needs to be seen by a professional.

Hello guys, I have a 99 Buick Century that has a very intermittent AC problem on norm or max settings. At idle the system cools for about 15 mins or so then the compressor cuts out for 1 -10 minutes with a quick cycle several times then resumes cooling. I also noticed this during regular city driving but could not tell if the quick cycling was happening. I attempted to charge the system with 1/2 can of 134 with leak detector but have not found any leaks. Any ideas are welcome before I visit the dealer.

Thank you!

If you can get it to cycle while idling, use a test light at the cycling switch (on the receive/drier, low side of the system) The switch should have power through it when a/c is working properly, when it begins to cycle, se if the feed side of the circuit is turning off or if the cycling switch is not making the through connection. This will tell you if it is losing signal frrom the dash end or if the cycling switch is going bad and cant handle the load for an extended length of time

my car blows heat and then blows cold air what could it be

Check the thermostat,coolant level and heater core-if all okay- check the air blend door/actuator operation

The driver side of my A/C is blowing warm air while the passenger side is blowing cold air.

There is a blend door for each side that determines how hot or cold the temp is. If it is warm and you have it set for AC, the blend air door must be sticking.

i have a 2000 buick century with 24,000 miles,i have dual comfor temp climate control.with settings down to the coldest settings the drivers side vents are blowing luke warm air and the passenger side vents are blowing ice cold air.

I have a 1998 Buick Regal and am having the same problem. Have you been able to solve the problem?

Its going to be the actual Ajdusting controler i had the same problem but with the pasenger side on a 91 regal. sins its has the passenger controler separet i could just replace it but if its the driver side youll probably have change the whole module and thats expensive!

why does my air only work on high

Most likely a faulty blower resistor

The blower has a resisitor pack that regualtes the fan soeed. Check the blower resisitor fo signs of a burnt connection.

How much should it cost to repair the air conditioning on a 2001 Buick Century? It does not work at all. Fan blows and heat works okay.

Not knowing what is wrong, I put everything that they may charge you. Add an additional 1 hour if your system leaks.

where is the drivers temperature door

My heat blows cold while it idles,but gives hot heat when driving.

You may need to flush heater core? The water pump slows down at idle, speeds up at higher rpms. Coolant flow through heater core slows down at idle. If heater core is restricted, even less flow at idle.

My Heat/AC fan stopped working a few months ago. Before it stopped working it would only work on max setting. I am wondering if I needed a new AC motor. Do you think that is the problem? Is there any way to check?

If the blower only worked only on high, I'd think there was something wrong with the resistor. I believe with the speed on high, the voltage bypasses the resistor and goes to the relay, then to the blower motor.

If you can get at the connector for the blower motor, you can take the connector loose, then run B+ and ground to the blower motor, to see if it will run, if it runs, you know the motor is ok. You should use an inline fuse on the voltage circuit to the motor.
I don't have any wiring colors, but, black is usually ground.

flushed and cleaned ac lines... vacumed and recharged system.... now high pressure side getting cold and the temp blowing out of the vents will warm up.. ? changed to orffice and replaced orings and no leask to vacum test...

why did you clean and flush lines to begin with? was their a problem to cause this? and what are your pressures? Not enough info to give a good opinion

i have an aircondentioning problem, think i need to replace relay but dont know which one to replace i see 3 or 4 of them . which one is for the air?

Thank you a ton, you have anserwed my question and now i know what one to replace ,, i am wondering if thhis relay can be tested? i realy appreciate the info. i have recived

easiest way is to just swap it out with a known good relay that has the same pin placement. or you can check out our tutorial on testing a relay at https://www.2carpros.com/how_to/how_do_i_check_a_relay.htm

Hi all, my 93 century a/c is not cooling .the compressor engages and runs very well no squeeks .The a/c freon lines stay the same temp .Any ideas of where to start?Low freon,bad relay of some kind,bad valve?

Sounds like low freon to me, or mabe a bad expantion valve. More than likely it,s probly just a small leak and it,s low on freon. It,s probably an R12 system and I would convert it to 134A.

The air conditioner blows hot on the drivers side but works as it should on the passenger side. The switch was replaced and it still does the same thing.

sounds like the mixing doors are somehow stuck could be a vacuum door or electronically controlled door, you wont be able to tell untill you inspect it.
