Try a test light on the wire on the compressor if it does not kick on. It should kick on in the a/c positions, as well as the defrost positions. See if someone can help, turning on and off the a/c inside the car ;)

2004 Buick lesabre refrigerant capacity

There's a label under the hood with that exact information. If all the freon has leaked out, you need to find the leak and repair it first. Then you have to use a vacuum pump for an hour to remove air that has entered the system. Then you add freon. 3 cans will do it, but use a pressure gauge to tell you when the system is full.

Timming chains....... engines not starting, just rotates and blows water out of the radiator when caps off. points and sparks lokks good, I sucpect, it might be the T/chains

Hello robtui: My name is Roger and I will help with your problem. The engine cranks over and does not start? Collant is belched out of the radiator? Problem is a warped head(s).Blown head gasket or cracked head. Remove the spark plugs fill the coolant system and you should see coolant fill and run out a spark plug hole. The engine should of had a miss before this happend. You could also do a compression test instead of filling the radiator and looking for coolant to run out. Either way you will find a cylinder compression leaking to the coolant passage. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

I have a 1994 buick lesabre. the car does not blow air or heat from the vents.. it only blows from the defrost vent. i also have the issue that the car only blows hot air when the ac is running.. i tried...

The air circulation system is designed to go into default mode if it cannot function properly. Default mode is defrost only. That could also be why your getting heat only. The main reason that the system goes into default mode is a vacuum leak. Check the vacuum servo motors that operate the vent doors with a hand held vacuum pump. They are usually located under the dash. If this is the problem then the freon level will have to be corrected or else the AC operation could be effected.

Where do I put freon in a 1996 Buick LeSabre?

usually the service port is located on the accumulator. this is the big can looking silver thing under the hood. although i dont recommend just throwing freon in it without the proper gauges to monitor the high and low pressure. you can damage the compressor and components. if your leaking freon having it repaired is more logical then adding freon and having it leak out again. hope this helps

My ac wont work

Must be Air-Condition System Lines/ Hoses leaking R12 Freon (gas).

DUE TO VERY LOW R12 FREON (GAS ) will not work.
Because there is a switch in the receiver/dryer prevent AC from working when low R12 Freon present, to protect the system & compressor damages.

You must fix the leaks, before recharging it.

They must **** the old (residue) gases from the system & lines / hoses...... & stay in the vacuum pump 30 minutes to proof no more leaks.

Recharge some oil for the old type R12 Freon gas.

Before recharge it to 62-67 psi R12 Freon
