Aux Fan Temp Switch in Receiver/Drier seized threads

[dieseldan44]

Hey AC gurus,

I was diagnosing my aux fan not turning on. Just got the system charged two days ago.

Shorted the switch and the fan turned on - I must have a bad switch.

Removed one from the parts car. Go to remove the one in the '85 and *snap*....$%&%^@%$^@%^

So I have a R/D with a brass thread stuck into it.

My fix is Im going to file down the surfaces to bare metal and JB weld another temp switch in to the R/D and call it a day. JB weld is thermally conductive so it should be OK.

Is there a better way? Should I consider something else with a lower turn on temp?
