Looking for insight/advice on how to bring my A/C back from the dead. I bought an 87 Runner that has factory A/C, but some of the plumbing is missing. Actually it only looks like a single line is missing. Never the less, the compressor and lines have been exposed to air for some time. Looking for advice on how to determine if the A/C system is in good enough shape to recharge. I assume (after replacing the missing line), the system will need to be pumped down and leaks detected. Can only an A/C shop do this, or can I get a vacuum from Harbour Freight or other shop to pull vacuum? How do I determine if the compressor is in good shape? Any input is appreciated. I know next to nothing about A/C.

Thanks,
Aaron

 

First thing I would check is the AC compressor. Make sure it isn't locked up.

Then go from there.

 

DC, quick tutorial on what/how to check the compressor?

 

Easiest way is to simply spin it. But make sure you are not just spinning the outer pulley, make sure you are spinning the compressor itself.

 

If the compressor has been sitting unused and open to the elements for a long period of time, then just replace it. The a/c compressor can and will go bad because of this, but who knows, you might get lucky and it might work ?.

 

Other than the compressor, is there anything else that would be suspect after being exposed to air? How about the dryer?
