'86 XJ-S
It’s getting hot in S. Fla… Adrianne’s A/C does not produce any cold air.
There is a leak somewhere and I’d like to locate it, but I do not want to
add any freon because it’s way too expensive and I have it in my head to do
a 134a conversion. Maybe.
I only checked the low (suction) side pressure at 2K rpm, ambient temp. was
87 F. The pressure was 20-21 psi. It’s supposed to be about 31-34. The
lines that are supposed to be cool are just as hot as everything else in
there. The electric fan starts when the A/C is switched on, and the blowers
work, too.
I also noticed the expansion valve is just barely visable in a hole in
the firewall, looking at it from the engine bay. Would this mean I would
need to remove that dashboard in order to get to it?
Any collective thoughts on the most likely place for a leak? I may be able
to borrow a leak detector, but I’m not sure now if there is enough pressure
in the system.
If by some strange coincidence a heat servo-thingy is not functioning, is
there a way to manually defeat it for a while? (I came to no conclusions
about this while following last week’s excellent thread about the servo
motor). This is not the problem, but I’d like to make sure I don’t have
this to contend with while doing the other checks.
TIA
Best,
Harry
