A sudden new noise heard from under the hood of my car!
I have determined The noise is definitely coming from the AC compressor. I can hear it when I lift the hood. The noise stops when the AC is turned off and starts when the AC switch is activated. I’m not certain if it is a bearing or one of the pistons inside?
Interesting is that there are moments that when the A/C is turned on, all is well, no noise and their is refrigerated air coming from the vents inside. But a mile or so down the road, the noise starts.
Also, once the noise starts, there is a tremendous load on the gas engine and the car has great difficulty getting to 35 mph.
The engine is a V6. the car is a SE model. There are Few bells and whistles.
There is 200,000+ miles on the car.
I don’t think it is a low freon issue, for is there not a built in safety that keeps the A/C clutch from engaging if freon ( or 134A in my case) is low? and when the unit does work, there is plenty of cold air.
I don’t think it is low oil in the compressor, as that would indicate a leak in the system , would it not?
Could I or am I , be looking at replacing the compressor?
Which will mean having to suck down the system, correct? and anything else I have not thought of that will be involved?
I am eager to read your replies.
