Thanks. Yeah, it was working fine until late last season. I think it was the right fan that actually came on first (lower temp), but I don’t' recall for sure. The left one is the one coming on now as soon as the key it turned on. I'll check it out after the holidays. Thanks.

There is no way to know from a distance which switch controls which relay and which fan.
It’s simple to figure out though. Turn on the key, nite the fan running. Unplug one wire from the top fan switch and if the fan shuts off, you have found the culprit. If it keeps going the presumption is then that the lower temp switch has failed. It will take a bit more work, but you can reach around from inside the wheelwell and unplug one wire from the bottom switch. The fan should then stop.
This presumes your system was working properly before and something has changed?
I suppose it’s possible that a relay could have failed in the ‘on’ position but that seems less likely.
