I've got a 93 5speed without a/c, so it didn't come with the e-fan. After looking I could see the plug that would be used if it was equipped with a fan, it was tucked out of the way and secured with a zip tie from the factory. So I went to the local pick-n-pull and got a fan, installed it and plugged it in. Well it doesn't work, I let it run on a 90 degree day and it just won't come on. Is there something I'm missing?
