Nissan Maxima: 1991 A/C Recharge Question

Bill G wrote: 

You can't do it yourself. It needs to be evacuated and recharged
properly (with special equipment). For what it's going to cost you, it
doesn't make sense to install an unknown compressor. Get a Nissan
rebuilt. I advise you to choose carefully who you have do this work.
It's not something your average garage that doesn't specialize in AC
work is likely to do right.

He's right. I've seen them go 10+ years making "buzz-saw" noises. The only
advantage with doing it now is: if this one does "explode" internally they
can spit trash into the condensor which will then have to be flushed out.
Ussually they just lock up and don't cause any other problems.

This isn't something you can do yourself as far as recovering the freon and
given it's probably an R12 car, I don't recomend "converting" it to 134a as
they never cool as good unless they were designed to use that stuff. I'd
leave well enough alone.

Be careful.... if it has been removed from the system, he should have
sealed the fittings with cap plugs to keep insects and such from
contaminating the inside. Even if sealed, the interior could start
to corrode if it has been "open" for a long time since the surfaces
are no longer protected by the compressor oil. The warranty is all
well and good but corrosion may not cause immediate failure, and it
could damage other components in the system.
 

Since you have a '91 I assume it uses R-12 refigerant, an ODS. In
that case... no, you can't do this unless you are a licensed
refrigeration mechanic (in which case you wouldn't be asking this).
You can't even buy the R-12 you'll need to recharge it. You will need
a pump to draw down the old system, capturing the old refigerant for
recycling or disposal, and to vacuum the system before charging it.
 

Yes (not really a repair...) be sure to have the drier replaced. It
should always be replaced if the system is completely opened.
 

Thanks for the responses.

I didn't get the A/C compressor. I'll wait 'til I have more money to spend
on it and buy a rebuilt and let someone else do the labor.

I did get a new driver's door control panel (locks/windows) while I was at
the junk yard. I haven't had a working driver's door window for quite some
time, so the trip wasn't wasted (I was going by it anyway). Got the panel
off a '90 GXE for $25. Swapped out the "used" buttons (for looks) and now I
can go to a drive thru again without having to drive slightly passed it so I
can open my door.
