I have usually seen 350 or so on the high side. After watching it a
little futher, it did drop down to about that range finally.
On the same project, I noticed the compressor was running ALL the time,
would not turn off even if you put in ec mode, would not turn off even
if you pulled the
PS, the fuel guage all the sudden started working, although it twitches
from time to time

I will checked that but iirc it was turning the right way. Will double
check it though.

Did you clean out all the crud stuck between the condenser and
radiator? My brother's SDL was about half covered with dead bugs.
No AC (bad compressor, fixed this summer), but it ran too warm on
long grades in West Virginia a couple years ago. Much cooler on that
trip this time.

No, have not checked that but I will. The coolant temp is just fine though.
The compressor is not stiff, the old one was though.

Replace it, it's shot. It's a thermistor, and I haven't found a way
to get the clip apart to solder in a cheap one.

Is if its shot it will cycle the compressor too much? Kind of what I
figured but wanted to make sure.

Yup. It has too much resistance, telling the PBCU that the
evaporator is too cold, so it switches off the compressor.
Leaving it jumpered (so that the PBCU thinks it's very hot) will
freeze the evaporator up.

For new
yea, I figured that out!! I will order a new one or pull one off
another car I guess. Think im going to drive it to work tomorrow so it
wont be running that long with it jumpered. I suppose its also possible
the wiring has resistance in it because the rats did chew completely
thru that wire
Anybody know how to check that evap sensor? Guess
that's my problem.
That sensor has a resistance versus temperature rating
chart. I've reproduced it in my troubleshooting checklist:

Converted to 134 and it seems done
the proper way it cools just fine.
At best it's only capable of about 80% of the cooling
of an R12 system, unless you changed out parts like
the condensor and/or evaporator. That may be good enough
for where you live.
My only concern is the high side

the slice is giving it some resistance.
Not much resistance compared
