2011 ram 5.7 ac condenser fan dead

[Robert Jones]

2011 ram 2500 st crew long box 5.7 l gas

Troubleshooting this far

10 am fuse was blown that drove the relay coil power .... fuse location m34
swap relay. test relay on battery .. goes click.

check for continuity thru tipm ..
check wiring..

fan motor is indeed dead.. jumped the connector with alligator clips to battery. will get new one once i figure out the relay issue. see below.

however ...
the relay wont activate when i start the truck and turn on AC.

My question is what conditions need to be present to activate the relay for the fan?.. is it just AC on? or does engine need to be hot? as well?

new fan works only after disconnecting battery. runs for approx 1 minute then stops. wont turn back on. i

i am assuming it is supposed to be on while ac is running?

Is your ac compressor turning on?

It seems that the fan only runs after driving. I took truck to Fargo last week and as I was exiting the highway and stopped at a red light , the fan came on.

Oh and yes the AC works
