Impossible. All vehicles sold in the US since 1993 use R134a. Either
your truck is older, or you are mistaken as to the refrigerant.
A shop that does not possess recovery equippment is not qualified to
do A/C repairs. Also, it cannot legally attempt refrigeration system
repairs. It can do electrical A/C work.
This means that they are smart enough to stay away from work that they
are not qualified to do.
That is one possibility. There are others.
You can do whatever you wish. I'd suggest that you find a shop that
knows how to do A/C work. For what it's worth, the low-pressure
switch should be mounted on a Schrader valve, and would not require
discharging the system for replacement. A competent A/C shop would
Cold air costs money. How comfortable can you afford to be?
Hardly. As it is sunday evening, no local parts stores are open. So,
I went to the Auto Zone web site and looked up a condenser for a 1994
Jeep Wrangler. At no point did they ask about R-12.
Go ahead and make something else up. I've got time.
Well I didn't spell it wrong, so here goes...
"Barrier" like in 'barricade.' Something that would stop
movement of something else.
The R-134a molecule is fairly small, normal AC hoses have
been known to allow R-134a to escape right thru the rubber,
much the same as how a Helium filled baloon deflates over
time because the Helium molecule can slip past the rubber
If you actually have the experience you claim, the term
"barrier" hose should not be unfamiliar.
"MY" = Model Year.
That's true. I did miss the word necessarily. I've "converted" several
systems, just by adding 134a to the existing system. No oil change, no
dryer change, no taking out the r-12. Yes, that's right, I have 3 trucks,
(2 fords and a dodge) in my fleet running mixed refrigerants. The whole
"conversion" thing is a bogus scam.
