Hello everyone. I have a 98 Grand Marquis GS and will post pictures soon. I have a question about my cooling fan. Sometimes after I drive awhile up to normal operating tempeture and I park, the fan will not shut off. It just keeps running indefinatly unless I turn the car off. This happens when the a/c is off and has not been on. It even happens in cooler weather. Temp gauge reads normal. All fluids are level and no codes from ECU or bad readings such as "soft fails" on scan. I had a soft fail from the MAF sensor once which gave me great fuel economy but slowly burned away my plugs with white ash from an overly lean condition. It finally died and caused the car to spaz out and miss under acceleration and even then tripped no codes! I think these ECU's are a bit mentally challenged.
What controls the on/off operation of the cooling fan and which part should I try replacing first? Thanks guys for your help.
