hey guys...I have a 93 & a 95 fleetwood big body... recently I noticed that the cooling fans were not running, I checked the fuses, the thermostat and the fans, I ran the fans direct to the battery and they work, I let the car warm up but they won't kick on....I have to run a straight wire to the battery everytime I ride out...anyone ever have this problem.... :(

The one on the drivers side is the primary fan, and comes on when the engine is over 215° only. That means it won't come on for quite some time if you're just starting the engine up and looking under the hood. The passenger side fan is the secondary, and only comes on when the AC is in use or in emergency situations.

You said you checked all the fuses and relays and everything is good, right? Hit your AC button and see if a fan comes on. Also, if you disconnect your coolant temperature sensor plug, both fans should immediately come on.

If all that is true, try this: Disconnect your battery for a while, say 1/2 hour. I was in the same situation as you last year, new coolant temp sensor, everything was good. I disconnected the battery for a while, and when I reconnected it everything was peachy. If that doesn't work, you could try running codes to see if anything is being thrown. Also, in the meantime, you can just run your AC to keep the fan on instead of doing the hardwire thing.
