The radiator fan in my Jeep did that in Sudan when it was 48C. Better to have it stuck on that stuck off in those temps!

I just tapped the relay with a wrench and it un-stuck and turned off.

Funny enough that was almost 5 years ago, and it hasn't done it once since in more than 80,000 miles of driving. Not in -35C, not in +45C. Odd little relay.
