Question about 1994 Buick LeSabre

1 Answer

1994 lesabre AC

AC comes out of defrost sometimes. Not all the time. Can hear AC compressor cutting on and off quickly sometimes. Not all the time. Had system vac and recharged. Worked good until next day. Doing same thing again. No leaks charge is full. This is not a consistent problem. Sometimes AC works good as new. Help before I start replacing stuff.

    I fixed it! I went under the dash and switched the vacuum lines around. I took the one for the defrost and put it on the vents. It now works great. I think maybe a relay or vacuum switch went bad. I don't really care because now it works great.

Air not coming out of vents

check under the hood and locate your vacuum lines going in and out of the fire wall, a number of times, vacuum lines can crack and sometimes cracked lines can seal, or leak.

1999 Buick Le Sabre Custom, My heat, and defrost work fine, but my car won't cool when I turn on the AC. My air conditioning is charged and the blowers work fine but why wont they blow cold air?

The first I would do is check if the a/c compressor is working. Start vehicle then turn a/c on in vehicle full power and then off/on a couple of times if you hear a click when turned on then compressor is working properly.If this is the case then you need freon.If not turning on,first check fuses,for location refer to owners manual,if not fuse then compressor needs to be checked which then you will need service manual purchase at local autoparts store.

Cold air comes out the defrost vent all the time. 1994 buick le sabre. no air comes out the front registers.

The most common cause is the blend door actuator. It's the door that diverts air between the floor, vents, and defroster. Sometimes the part will get stuck in 1 position. Some cars have cable driven blend doors, others are electronic.

Radio, lighter, and air conditioner on 92 buick le sabre and lighter won't work at all, air conditioner won't recognize being turned on anything but defrost and defog. Could it be...

Check for a fuse that indicates radio and replace it if it's burnt through or melted or discolored. The Buicks have dash controls that require expensive repairs sometimes to get the temperature controls to work so some people jump around the controls by installing a separate toggle switch that directly turns the AC unit off and on for 92 through 94 Buicks. Any AC shop can install the bypass wires.

95 Buick lesabre, when defroster is turned on puddle of water forms immediately behind driver seat.

If you have the smell of Coolant then you have a leak in your heater core. You said immediately so that is the first thing I would look for. If there is actually a bit of time before it forms I would check to ensure the drain for the AC condensor is clear as when the Defroster is on the AC unit also runs. If you think this is the problem and want a quick fix, disconnect the Wires from the AC Compressor and it should stop the problem.

Air not coming out of vents

what your problem is that you have a issue with the vacume system, what i did was removed the bottom panel on the passenger side looked up and you will see a bunch of wires, look for a black box (should be right above your head by time you squeeze in there and it has a yellow/amberish type of color you will see that you can remove this its a rubber piece cut the pink tube on the side about 2 inches away from the plug assembly, and slide it into the blue tube this will bypass all controlls and shoot the air out of the front vents, you WILL NOT beable to set it to defrost max/normal or htr (mainly which vent flaps are where) this has worked formonths and the a/c acts as if its on normal mode to use the heat just slide the switch :) until you can test all the other equip this will keep you cool or warm
