So. 1978 Fj 40. Bone stock motor/carb still has smog equip etc. does have new radiator and hoses
Carb fan will not come on. I have read ALL the threads and have done the following:
1 cleaned and inspected all connections from temp sensor to fan and all points in between
2 checked the in line fuse on passenger side firewall. It was the original fuse. It was blown. Replaced it
3 took carb fan module apart and inspected all solder joints. Looks as new ( it is a very clean FJ under the dash and wiring )
4 pulled the switch off of the fan and hooked it direct to battery. Fans runs strong and fine when direct wired
I’m out of options. Ideas ?
now I do live the the pacific NW. it does not get very hot here although it will be 100+ for the next few days ( very unusual here). So I did read that it simply might not be getting hot enough to activate. I had a 79 and it did not matter if it was 60 degrees and raining. That fan came on every time when I drove the rig and ran for several minutes after shutting it off.
is there a way to manually activate at the sensor to ensure wiring is all good and it is just not getting hot enough? Take sensor out and heat it with a lighter? Manually ground it to activate? I’m out of answers
thanks in advance
