'93 Sable (3.8): A/C problem
I have a 1993 Mercury Sable GS with 3.8 engine.
In August of last year with the A/C running, the car started bucking
and then there was a burning smell in the vents and I shut off the
A/C and the bucking vanished and the car ran fine.
I didn't intentionally turn on the A/C again until recently.
I find out by accident that I can run the defogger setting for ~30
minutes with no problems but then it will start doing the same thing:
bucking and die (if at idle), though no burning smell.
Also, I can run the A/C on Max A/C, full fan but the air temperature
does not change. And, like the defogger, the car doesn't buck or die
for the same timeframe (~30 minutes) with the A/C on.
The compressor was replaced in 2002 and accumulator in 2003.
Do you think my compressor is shot or is there another possibility?
Thank you for any ideas.
