I have a 99 Taurus 3.0 Duratec, AX4N, Climate Control, owned from
Never any problem with A/C cooling, tho a few electrical problems.
Regularly driven til last year, now about once a week.
Not cooling when A/C first used this year. Compressor
short-cycling...so I assume there was 'some' pressure in the system.
I should have checked static pressure first.
Hooked up the gauges and added a little 134 (30 lb tank with over 3/4
left) . Compressor cycles got longer and air got cooler. The high
side gauge fitting started leaking, so I aborted the mission. Probably
leaked it right back out. Now back to square 1...no cold air.
So...once I get the gauge fixed, any suggestions as to what pressures
I should see at, say 80F?
I know basic A/C theory, and have had moderate success working on my
own cars before...or...I know enough to be dangerous :)
I know the 'right' way is to have it evac'd, tested, recharged with
x.xx lbs of 134, tested again, etc. I'll do that if I have to; but
I'd like to get a handle on it first.
