I had put a new cooling fan blade on my friend's NA 16v 900, and we fired it up to make sure everything worked.
Pushed the snowflake button, both fans came on, and the air in the car started to get nice and cold. The car ran for a while, and no overheating of the engine. He was happy, so off he went.
A bit later, the A/C started getting warm and the coolant temp needle started going up. He pulled over, and the cooling fan was not working...not the A/C fan, but the radiator cooling fan. He checked and the fuse was blown. Put in a new fuse, and the cooling fan still didn't work. He drove it home.
Any ideas? He says he just put in a thermo fan switch not long ago. I told him if the cooling fan isn't coming on, it's either the fan motor or the thermo fan switch...and I missing something? His cooling and A/C look exactly like mine and mines an 87 NA 8v 900.....
I know the A/C WON'T work if the car temp gets too hot, so that particular switch, located in the passenger side radiator hose, is working....when the car overheats - the A/C kicks off. So what's shutting down the radiator cooling fan and blowing a fuse?
If the thermo fan switch for the cooling fan goes bad, would that blow a fuse? If the fan motor it'self was dying, would that blow a fuse?
The last time I looked at the car, all fans were turning and A/C was cooling! WTF?
Any help appreciated!
