Testing electric cooling fan
Hey guys, been a while since I've posted (mostly since everything is going so smoothly with the racer) but I have hit a snag.
When I just removed the entire A/C and Heating system on the vehicle. I bypassed the heater with a bit of hose looped and got an A/C Bypass pulley for the belt. I reassembled everything, only leaving a few clips unplugged, all of which went to the now uninstalled A/C and Heater system.
As I always do, I restarted the vehicle after the process was done to make sure everything was working properly before I started the next item on the list. The 'bird fired right up and ran smoothly, but the cooling fan never activated, regardless of the engine temperature. I never let the vehicle overheat, but the temp did rise above normal operating before I ultimately shut it down.
I have since pulled the cooling fan to examine it, but it appears to be intact. I have tried an old trick of mine (briefly wiring the fan up to a 9 volt battery) and haven't even gotten a jiggle out of it. If anyone else knows of any fan-testing methods, please let me know, otherwise I'm going to end up at a pick and pull looking for a new one.
By the way, it is a '97 Thunderbird 4.6L with the sport package, in case any of you are wondering.
