Hello dudes, I just replaced my radiator, probably a week ago and I noticed today it was overheating, one of the connecrors on the fan module had come out, I plugged it back in and while I was doing that the fan kicked on and off a few times, but now it won't turn on at all, I was wondering if anyone knew where the ground was at specifically for the SS ive sprayed electronics cleaner on the plugs. The fan was working fine before I changed the radiator so I must have knocked something loose
p0480 just popped up
So i have tested the fuse, tested the radiator with a different power source (works), tested the incoming power line from electrical harness, 3 prongs, 2 big ones, one small, one post on the big tested for 13 volts other one 0, small prong tested at around 3 volts. I'm stumped as to what to do next
You know, I did just recharge my ac system today, last week I had a helper unscrew a fitting in the AC condenser in front of the radiator when I was changing it and I heard a bunch of hissing and the AC didn't work afterwards, I overfilled it perhaps. One of the links said the AC condenser pressure sensor could cause this
The P0480 most likely popped up when the engine was on and you disconnected the PWM module. What was the engine temp when you were expecting the fan to come on? If the AC is disabled the fan won't run if you turn it on.
P0480 means that 0 voltage was sensed when the fan was commanded on.

Actually It was when I was refilling the AC, the fan never came on, I did know the fan should have been running if that was on and after about 15 minutes of idling and it not coming on I checked and that's when I discovered the radiator fan not plugged in (not from the wiring harness, the plug on the other side from the fan to the module) I also found out of you don't push it in super hard until you feel it click in it will pop out 🤐
I should have been more clear, the AC just didn't blow cold air after that, it was not disabled. Everything still worked normally except it didn't get cold
The question is: is the Compressor working? Not: is the AC on.
If "Everything still worked normally except it didn't get cold" That means the compressor is running but something is very wrong; the compressor won't run if there is too much or too little freon.
