94 lesabre cooling fan fuse

[Steve P]

HELP! My 94 lesabre keeps blowing the under hood fuse for the cooling fans. Is it one of the relays?

Try disconnecting the connectors at the motors one at a time. If the fuse does not blow with the fan disconnected and blows with the fan connected, then the problem is likely in the fan itself.

You could also pull the relays which are the two near the firewall closest to the driver's side and replace them with others along the firewall since they all should be the same type.

You most likely have a cooling fan that works, but draws a huge amount of current to make it work, which means the fan is about to give out. My wifes Buick had a cooling problem and overheated in traffic on us. The fuse was blown and replaced. However, the engine temp was still "all over" the place, depending on accel, the grade going up, speed, outside temp, etc... Then one day, taking her car to the store, I smelled an electrical type of burning coming through the vents. I shut off the vents and everything else, and the smell went away. When I got home, I opened up the hood, but the engine was too warm to 'feel' around, but I could smell the burning in the engine compartment. I let the engine cool for about 20 min., then started to feel & sniff around under the hood. When my nose detected the electrical 'smell' directly behind the radiator. I spun one fan by hand, and it was fairly smooth and free, and the motor casing was warm. I did the same to the other fan, and it's casing was VERY hot! Just that simple fan on it's way out was the cause of the cooling problems all along, that several garages could not find. Using the warranty we bought with the car, we had the cooling fan replaced and the system checked out, and the temp gauge now holds steady, now matter what the driving conditions are. The relays merely switch power to the fans when the sensors tell them to do so. I would look closely at the fans themselves. Good luck.
