Re: [DML] AC went "POOF!"

[Rod Dillman <rhdillman@xxxxxxxxx>]

Robert, The symptoms you describe sound identical to what happened to my 78 Eldorado. I had driven to Autozone with the AC on, and was walking back to the car after shopping. A loud bang under the hood sounded and a white cloud of "smoke' appeared. Naturally a crowd of onlookers gathered , when I popped the hood it was clear that a pressure hose to the AC compressor had burst at the fitting. New hoses with the correct end fittings were no longer available, however the shop knew of a place the send the old hoses and they were able to use the old fittings and rebuild them with new hoses. The Eldorado had been converted to 134a several years before this happened. Look for the source of oil residue, it will help you pinpoint the leak. It may be a good time for you to replace all the AC hoses with new ones while the system is down.

I hadn't driven it for about a week, 
it was about 100F and I had the AC pumping full. 
I was sitting at a stop sign about a block away from my house, 
(the car had been running only a few minutes) 
and there was this loud discharge from the engine, like something
pressurized had popped, 
I could see a spray of smoke in the rear view mirror coming from 
under the engine lid. 
I quickly turned the car off. 
The car was not over heating, or had even warmed up yet. 
I guessed that I had blown a water hose, but there was no water! 
No oil, no grease, or no sign that any thing was discharged. 
There were no holes, busted hoses or anything visibly wrong. 

I cranked the car back up and it started and ran just fine.... 
...except no AC! 
The fan was going but the compressor would not kick in. 
So I must assume that the explosion was my R12 shooting into space. 
The problem is, I can not figure out from where, or why? 

Does anyone here know what happened and what I need to do to fix it? 
Should I take it to a Volvo dealer, or someone that deals with older
Euro cars and what parts should I refer to as far as compressors and
hoses? Is this standard stuff they will recognize? 

Thanks for the help.
