Fan Switch Part Numbers
Recently I was having trouble with my fan coming on automatically and started researching part numbers for the fan switch and the various different temperatures that they are configured for. I found that a lot of the part numbers in the existing threads were outdated. After a bit of research I decided that I was interested in these two AC Delco parts:
AC Delco: D1852B GM: 14043276 (On: 220F Off: 204F)
AC Delco: D1855B GM: 14043275 (On: 229F Off: 213F)
Hopefully this helps save some time for people.

I went with the 212* Switch. I like that it turns on sooner.
