radiator fans not working

[jasonfreeborn]

right my radiator fans are not working i thing the slow speed fan works as when i put the a/c on it comes on. normaly the temp sits at 80 but when i sit in traffic it goes up to 90 100 ish but the fans dont cut in ive had someone test the fuses and there ok so the problem could be the fan switch not sure

on the d9s when you take the front grille off theres 2 control units on front of rad fan housing-im not sure if yours as these but its worth having alook,
My Fans dont kick in till they go way over 100 dont know if this is normal
it sits on 90 all day long and doesnt over heat tho so im not worried,

is your car overheating ?
if not it couid be just a faulty temp sensor,
