Need Cooling System Help
Hey guys,
I'm in need of some cooling system help- mostly related to cooling fans.
Here's the information I have:
- Vehicle was in a front end collision (had to get radiator, A/C condenser, and cooling fans replaced)
- The horns don't work (might be related to the fans not coming on)
- Needed to get the cooling system bled which I pretty much already did for the most part (if I'm not mistaken)
- Car isn't street driveable yet but I drove it back and forth in a contained area and the temp gauge went up to like 3/5 without fans coming on
- Temp stays below halfway point at idle
- Temperature sensor is good and I tried to connect a pin into the temperature sensor plug for a direct connection (car was showing temp all the way at H and no fans came on)
- I checked the relay under the hood and it seems to be working fine (makes that clicking sound when given 12v power)
- A/C fan doesn't come on when A/C is turned on (don't believe that the AC system is charged all the way- not sure if that contributes to it not coming on)
- I have two fan control modules, the original one and the used one I got off a parts car and neither work

- Also, upon startup, lower hose is cool and upper hose is hot. After a few minutes, both hoses become hot. Is that a symptom of bad thermostat? I think I also see a sensor attached to the thermostat.
- I press on the horn and hear a clicking under the hood in the relay box. Horns test out good when giving direct power. Could it be a bad connection on the harness somewhere? Maybe it's a bad ground? The fan wiring and horn wiring look like they're coming from the same group of wires. Also, my headlights aren't installed- neither is my ambient temperature sensor- this wouldn't affect anything right?
I feel like I'm almost there. Please help if you can!
Thanks!

UPDATE: There is a fuse that sits right on top of the battery. It's a 50 amp fuse that apparently goes bad when you try to jump start the car- which I know I did before.
Anyways, replaced that fuse and the fans now work!
