2012 Ram 1500 electric auxiliary fan(AC condenser fan) won't turn on when low speed relay is bypassed in TIPM.
Anyone have any ideas why?

If I jump the high relay, which is on the horn bracket,the fan comes on.Does it run on high. If not likely the fan motor is not working. Are you running a hot lead right to the fan, if not it could also be the wiring between the TIPM and the fan. Could be the connector at the fan also.
Thank youComputers
We have to be careful jumping stuff out in the relay and tipm now a day
It could result in blowing out the PCM driver that actuates that relay.
You can certainly simulate a closed or open relay by closing or opening the circuit to 87 / 87a but be careful around the control pins on the relay. Sometimes the computer (module, PCM, BCM, control head) applies power to actuate the relay and other times the module provides the ground path.
I hope this helps you.
Please return and tell how this information worked for you, what you find, and how you eventually fix your vehicle (even if it is that you brought it to a mechanic / dealership for repair)
It is your feedback and final repair report that will make these forums useful to others in the future.
Many times I search and find the same exact fault that I am having, someone suggests how to fix it, the patron follows the suggestion and then never returns to say YEA! or NAY...
The forum thread just goes dead because the person fixed their fault and has not a care to offer the answer anymore. Please don't be that guy.
Cheers!

I have posted on 4th gen also..one guy told me to trace back wiring and look for corrosion which I didHey jerbo1978, the guys in the 4th gen RAM forum may be better able to help you over there. This 3rd gen is 02-08 and your a 12
Not that I (we) are giving up on you, rather this may be a 4th generation common fault that the guys can tell you to 'wrap a wet sock' around something or such...
They might be able to say right away.
