Cooling fans not running
90 LS 400 127,600 Miles. Engine Warning lights came on. Cooling fans not running. Engine compartment seem extremely hot, although the temperature was at midpoint on the temperature gauge. Can someone suggest probable cause and the proper steps to check it out.
Thanks
Thanks

Check to make sure the fan clutch is not locked. With the engine off, see if you can turn the engine fan. If you can then you should be good. I don't know if I've ever seen the cooling fans in the front running. If you're still worried you may want to replace the thermostat.

Thanks for your help. Checked the engine fuse (5 PIN) under the hood. Seemed ok. Put it back in.
Started engine, warning light went off.
Slight corrosion on the pin I guess. I'll keep My eye on it though.
Thanks Again

umm.. that ecu fuse just clears the code temporarly and it will turn on back again. You could always borrow a OB1 scanner or do a self diagnosis on the engine code to find out exactly what is triggering the code.
