Default Cooling fan not coming on like it used to.

The first cooling fan does not come on like it used to. When the air is on the fan works. Any ideas is there a relay that might be bad. And also it doesn’t come on after it’s parked. It used to come on when parked after a ride. Thanks

Are you saying one of the two fans aren’t working?

No it works when it reaches about 210. But it used to come on for a bit as soon as you turn the engine off.

BOTH FANS RUN TOGETHER!!
At low speed they are series, at high speed they are parallel.

If only a single fan is running, something is seriously WRONG.

I’d start with disconnecting both of the fans or better yet, pull the fan assembly out (two bolts) and ohm check both of them. You probably have a fan motor going bad (high resistance).
