Makes sense.

When I bought this truck in 2002 the A/C did not work on low, but worked
on setting 2, 3 and 4. Like you, the lower settings began to cease
working until only hi worked. If I had known all I needed to do was take
30 seconds to replace this part I would have done it in 2002! How nice
to be able to take it to the gas station this morning with the A/C on
low! The fan makes virtually no noise on low and keeps the truck very
chilly.

I still have the original A/C system in this, meaning if anything ever
goes wrong I have to upgrade it to the new type of A/C rather than
repair or service it. Do you still have the original A/C in your '88?

IAC it blows cold as a freezer, so no problem there. I know some people
adjust the temp slider to mix some heat with the A/C when it blows too
cold. Does this slider adjust down the amount of freon being used, or
merely introduce hot air along with the cold? That's probably a stupid
question, but... ;)
