2007 grand marquis p1299 reading. cooling fan does not run on a/c or ever. only overheats in long idle or heavy slow traffic. coolant topped off 50/50. ok to replace fan and module? or test other?
ok to replace cooling fan or should other things be checked out first? dealer says its a common problem and new fan and module are upgraded replacement parts. confirm easy enough to do on own and not necessary to
empty out coolant. radiator looks clean.
