Resolved Question:

I have 2000 Oldsmobile- Intrigue and I believe I may have a leak on the freon side of the air-conditioning. I've just recently have it charge (two months ago) with freon and the technician noted that I have a good compressor and that a once a year freon charge is necessary for this kind of freon (134a) type.

However, it is not producing cold air again after only two months of freon charge. I have two A/C temperature contoller. One in the passenger and the driver side. The driver side is the one that does not produce cold air but the passenger side is.

What can I do to get it fixed before going to a qualified tech. and maybe have a good understanding before they will quote big dollars with out me knowing what could be the problem.

Hello,I will be glad to try and assist you with this,Welcome to Just Answer.


ok the reason why one side is cold and the other isnt is because the vehicle is low on freon,it will cool one side but not the other when it gets low as there isnt ebough freon to cool both sides and the closest side of the vehicle to the evaportaer will blow cold and leave no cool airflow for the other side.

The vehicle shouldnt need recharged once a year(bogus)once a system is charged and if the vehicle keeps the freon in the system(no leaks) then it should only have to have a one time charge unless another leak has sprung.

What needs to be done is the system needs to be checked for a freon leak,if the freon was recharged last with dye added then someone with a dye detection light can look over the ac system to find where the freon is leaking out at.

Some of the most common are the condensor,and ac compressor as well as possibly a freon line/hose.

If dye hasnt been added to the system then the system can be pressurized with nitrogen up to 200 psi or 250 max to see if the leak can be pinpointed,you should hear it hising out if the leak is signifigant enough,also the components in the ac system can be checked over for oily residue leaking out around hoses and components,if residue is found then this would indicate the area of the leak.

It definately sounds like it from here that the vehicle is low on freon again and needs to be checked for a leak in the system then recharged one last time once the leak is found and corrected.
