Electric Fan?

[t-topflyer]

1987 had to move it today. Been a while since I've cranked it. Everything functioned normally the last time I drove it. It's 36 degrees outside today. I noticed the electric fan running which is unusual as it usually only comes on if the A/C is on, or the car is up to full temperature on a warm day. Neither of these were the case today. Any ideas?

Disconnect the fan delay relay. Useless part of your car. It degrades with time and will run the fan even with the car off.

That's the thing and I understand that, but nothing was on at all as far as climate control.

Are replacements available? Will the fan work at all with that disconnected?

without delay relay the fan works fine

T-TopFlyer, if it's your STOCK electric fan motor that turns out to be toast... let me know as I believe I have a few good used ones.

Thanks. The fan works fine. It's just on when it shouldn't be, all the time that it's running regardless of ambient and engine temperature or even when A/C isn't on. I've read that it might also be the cooling temperature sensor or fan control module.

John Spina from Caspers in on the board from time to time... guaranteed he will know what your issue is... he is a electrical genius.
Hope this helps.

Car does have a turbo tweak chip. IIRC it is programmed to come on at a lower temperature than stock, but I don't remember what temperature that is. I guess it's possible that I may have not noticed it coming on in the past and just found it odd that it was on at such a low ambient temperature,
