Hey all, recently picked up a 17 FiST. Replaced the radiator after it overheated 2x and noted it was a common issue. After the replacement went in the radiator fan would not turn on (low or high), and the fan was working fine prior to replacement.
edit: the fan will not turn on with the AC on
So far I’ve done the following:
-Relay tests fine (75ohm across the coil)
-I have 12vdc at the plug leading into the module with the car running and/or ignition on
-I have 12vdc at the plug out of the module with the ignition on (I had to pull the IC pipe to get unplugged, have not put the piping back in to test with the car
-The fan spins when connected directly to 12v
-No CEL
-noted cracked wire insulation on both the power and ground wires at the engine harness plug To the module and insulated with e-tape as a temp fix.
Are there any specific resistance tests that can be run on the module?
I was going to test the coolant temp sensor but debating just replacing it since it’s relatively cheap.
I would generally assume it’s unrelated, but I changed the coils and plugs at the same time. I also have the headlight housings out of the car. I pulled the crash bar and rad support as it seemed easier, but everything is plugged back in as it should be.
