Radiator Fan not working (maybe a unique issue)

[gsrdriver92]

I have a 2012 Liberty Latitude with recent issues related to the radiator fan and AC blower motor. When I first discovered the issues, in troubleshooting, I had the radiator fan replaced (the case looked corroded), then the AC blower fan (in dash). While the radiator fan was working, the AC blower motor still did not work. It turned out that the TIPM TEMIC fuse box assembly had a short in it. I had the fuse box assembly replaced with the mechanic programming it. However, I discovered that the radiator fan does not turn on. I used a computer diagnostic tool to see if I had any error codes and there are none. I checked the radiator fan fuse too. No problem. My vehicle does not overheat, it now runs hotter with the needle on the temperature gauge just shy (to left) of half-way. I thought I would ask the forum for any advice on determining what is wrong. Could it be programming for temperature to turn on the radiator fan? Thanks for any help.

Did you check the relay and control voltage on 85-86 pins? If you by pass the relay jumping 30 and 87 will the fan engage?

I would second Blackhawk’s recommendation to check the relay. I had an electric fan issue on my 03 Liberty and it was caused by a bad relay. On the 03, it’s bolted to the frame under the fuse box assembly, where it’s subject to getting splashed with water a lot. It was also a real PITA to get to.
