Default C4. Cooling fan

I am trying to locate the problem why my cooling fans will not come on. I’ve checked all the fuses and they are good but the fans will not come on. I have a 1996 Corvette

Welcome to the forum. Assuming that the fan is not working on any of the speeds, you'll need to take a voltmeter and find out where you're losing the 12 volts to the fan. You can start at the fuse block and trace it to the switch and then trace from the switch to the fan and I believe there is a relay for the high-speed fan function. Also you can check the blower motor resistor that's in the airstream for cooling purposes that controls the speeds.

You're welcome. If you don't have a factory service manual, there is at least one aftermarket Corvette supplier that sells just the schematic. I'm sorry that I don't remember which one it is but I'm sure a quick Google search will yield some results.

My money is on the relay. These Vettes are full of 'em!

Default Cooling fan

I have a C4 1990 had problems with my cooling fans one was tied up neither one of them were getting a signal to work as it turns out I replaced one of the fan motors took it to a shop and had them prepare to let the cooling fan run constantly my AC is inactive the other fan that was working does not work right now the one fan is cooling the engine down no problem at this time so check and make sure your cooling fans aren't tied up
