'96 850 A/C compressor over temp sensor/switch?

This is the part that I'd be worried about since I really don't have
that much experience working on cars...

There's no real knowledge required for this to be honest, just patience,
tools and rubber arms.

Nothing needs to be disconnected, just removed so it's just a time
consuming unbolting job. I would be interested to know the labour price
though because it took me about 3 to 4 hours to get it all off (first
time) and a couple to get it back on again. Frustrating if you're
paying servicing prices because the actual shim removal takes just a
couple of minutes, it's getting to it that takes ages.

Well, it didn't work. We took it out shopping today (about 90 deg. F
outside). It worked great for 10 minutes and then gave up, as usual.

Could it still be clutch shims?

Ho hum...

sorry to hear that...I'm still going to give mine a go tomorrow and see

Yes, probably. You can try wiring a relay into the circuit, which will
give the clutch a higher voltage, allowing it to work for ?

Find one of those common 1 cubic inch 4 or 5 pin Bosch type relays.
Mount it under the fan shroud top where the other relays are. Run a
wire from the battery through a fuse to pin 30 on the relay. Run a wire
from pin 85 to ground. Connect the wire that goes to the clutch to pin
87. Connect the wire that was connected to the clutch to pin 86. If
you have a 5 pin relay, you can just ignore the 5th pin, which may be
marked 87, 87a or 87b. And if you have one of those temperature
switches that you just disconnected, you can cut the terminals off an
reuse them for this job.

In my view that was always the likely suspect in the first place. :)

Yep I had the same results. However I consider it time well spent. If
I go ahead with the compressor replacement next summer, I will take
comfort in knowing that I at least tried and checked that it wasn't just
a bad switch.

Could it just be the clutch gap? Sure, but based on what I've read here
it sounds a lot more involved to test/fix.

Since I love the car otherwise, I'm willing to save up to get the
compressor fixed next summer.

Thanks again everyone for the help/advice/pictures!

Yes it always probably was the clutch gap. :)

Fixing it is just a spanners and time job, nothing more.

1. Unbolt annoying stuff that's in the way
2. Remove clutch, remove shims, replace clutch
3. Rebolt annoying stuff

It'll give you something to do over the winter.
