[DML] Re: AC went "POOF!"

[Travis Graham <tgraham@xxxxxxxxxxx>]

Hi Robert,

If it had dye in it, you could get a UV lamp and some goggles and go  
searching for the source of the leak.  It seems to be standard  
procedure to add some dye when getting a recharge and if it's there,  
you can probably see some evidence of dye around the service ports.   
But, the only AC parts in the back are the compressor and the two  
hoses which run to the condenser and accumulator, so there aren't too  
many places to look!  Check the 14mm bolt that holds those two hoses  
onto the back of the compressor - if it were to sheer off or become  
loose, that would certainly cause rapid refrigerant loss like you  
experienced.  The hoses don't thread into the compressor, this bolt  
simply holds them in place.  If that's not the problem, look for  
holes in the hoses.

The compressor won't run if there isn't enough refrigerant in the  
system (which there clearly isn't), so you shouldn't condemn that  
part just yet.  While you do need equipment to deal with the  
refrigerant and recharge process, if you feel comfortable doing it,  
you can certainly replace the components on your own.  And some of  
them won't cause too much pain to replace!  The orifice tube and  
accumulator were mentioned, also be sure to replace the o-rings along  
the way.

Good luck.
